He first appears in "Butterfly Effect", and since then, he has made many other appearances and cameos. In "Intern for the Worse", he returns as the main antagonist.
He appears to be a smug opportunist and a swindler[1] where he manages to cheat each Loud sibling by giving them "Lily's blanket" in exchange for their garage sale money. Despite him changing this behavior in "A Flipmas Carol", he has since reverted back to his old ways; in "Farm to Unstable", his store was revealed to still be selling expired milk and eggs, and in "Frame on You", he forced Lincoln and his friends to pay him every time they asked him a question.
In "Out on a Limo", Lincoln states that he never gives him free smoothies, which means that Flip is stingy. This is also proven when he charges Papa Wheelie for double strawling his Flippee.
In "Intern for the Worse", he comes between Lincoln and Clyde's friendship, by making them compete for higher ranking staff positions at his store, much to his advantage.
Flip is also a very repulsive man, as seen in "Intern for the Worse" where he sells expired milk, and uses the melted cheese machine to put his dirty clothes, mostly his socks. He also falsifies lottery tickets with a black marker. The oil he uses in his store was actually hot dog grease. His disgusting behavior is shown again in "Roadie to Nowhere", where he has so much gunk on his teeth which Rita tries to remove. He also has a false tooth made out of beef jerky.
He cares a lot for his profits, but has no regard for safety or lives of his customers, because in "Washed Up" he let Louds hire a broken boat from him. He blamed them for ruining it, despite it was his own fault. In addition, in "Snow Way Out", he would have abandoned the Loud children and Hops if not given the tickets, despite them being in danger of developing hypothermia.
Flip is also an opportunist, as seen in "Last Loud on Earth" he used the storm as a distraction to steal some burgers from Burpin' Burger.
He does not care if food is cold.
In The Loud House Movie, he is shown to not like singing or pity parties as he kicks Lincoln off his property while he lamented about his sisters being more successful than him.
In "Much Ado About Noshing", Kotaro explains that Flip siphoned the drinks from Lynn's Table with his van but got livid when he was told give everything back. Later, Flip received an invitation to Lynn's Table as an attempt to see who the bad reviewer was.
Appearance
Flip is a middle-aged man of short stature. He has gray hair, and a bald spot on the top of his head. He also has a gray mustache and eyebrows as well. He wears a brown pants, black shoes, and a t-shirt that was originally white in Season 1, but changed to red from Season 2 onward. In "Intern for the Worse", he wears a red button-up shirt.
In his teenage days, he used to be slimmer with longer, black hair. He was also clean-shaven during his time in middle school until he grew his signature mustache after being swindled by Scoots on the night of his Christmas dance.
Trivia
According to Lisa, Flip is the only person in town who will hire a four-year-old with no experience.[2] It is unknown if this is true, or just part of Lincoln's fantasy.
The fact that he cuts corners, tampers with the expiration dates, and has unsanitary conditions with the food he sells, is similar to Apu from The Simpsons.
The fact that the slushies he sells have their own name, are similar to the Squishees, that Apu sells at the Kwik-E-Mart.

Flip owns a Humvee, which he uses as a snow plow.[3]
He has bad dental hygiene which he states that running his store was more urgent, and furthermore, according to Rita, his appointment has been ready for ten years.[4]
In "Net Gains", it is highly likely he has been to prison before since one of the inmates recognized him as both he and Lynn were driving by.
He also runs a pawn shop business called 'Pat's Pawn and Prawn', a ticket reselling business called 'Tucker's Tix and Tux'.[5]
His great-great grandfather, Gip, founded the first ever business in Royal Woods, called "Gip's Girdles 'N' Garters".[6]

Around the time Lynn Sr. first met Rita, he is seen with brown hair instead of black.[15]
Lincoln believes he is lactose intolerant, and he at least is in Lily's dream.[17] However, it is unknown if this is true or if Lincoln and Lily just think it's true, since he's eaten cheese before with no problems.[10]

When he sits on the Louds' dining room chairs, his butt falls asleep.[19]
According to Clyde, Flip once threw out a kid for loitering while his mother was paying.[20]
When he was a teenager, he was friends with Rita and Chef Pat. Though his shenanigans often annoy Chef Pat enough that he flees from her wrath.[21]
