[TOMT][TV-SHOW][2010s-2020s] Looking for a joke in a tv show.

I'm looking for a joke in I think it was from an animated show.

One person asks one of the show charachters at a party if they are friends with a famous person (I forgot the name of who). Than the character says "yeah we friends, no we friendish, no we friendlish".

After that a white text pops up with the definition of friendlish and it says: "friendlish; not actual friends'.

Help would be appreciated :)
