This is the French word for grapefruit, but it is also slang for 'fatso'.
Mangez plus, Pamplemousse!
why, yes, it's an insult to call someone a grapefruit, in french.
"OMFG! Way to go, ya fucken pamplemousssssssssse!!"
Pamplemousse is a person that everyone wants in their life. They are totally awesome and don't have many friends, yet they cherish the ones they have. They get drunk often but pretend they're fine, even if they get alcohol poisoning. They sometimes watch shrek movies and poo, but that's okay. Dogs are good at cleaning that kinda stuff up. They like French a octopi, and they have peepeepoopoo syndrome and white eyes.
An annoying, pesky, person who is immature.
"Hey, you know that boy over there?" "Yeah." "He's a pamplemousse." "Oh, I'll be sure to stay away."
