Laffonk
A kid who gets his butt kicked in an argument but still yaps like a stuck pig. He'll call you names and throw blame like it's going out of style until you're too tired to fight back. You might end up laughing while he's left looking like a fool.
Bro, you're a Laffonk. I beat you in the math test, and you're still arguing like it's the final round of a championship.
You're a Laffonk. I beat you in the video game and now you're crying like a baby.
You're a Laffonk. I beat you in the debate and you're still talking trash.
