A little bitch who is a poser and follows his friends around. He can usually be seen behind a group of friends saying random memes for no reason. But even worst he is gay.

Leonard’s are usually a fat scamming and betraying pieces of shit. They scam their friends and snitch on their friends. They beat their family members and have a drug dealer family member. And he’s addicted to fortnite.
JJ- Leonard scammed me and swore on his family’s life he would pay me back.

Damien: OMG I WANNA SET LEONARD ON FIRE BECAUSE HE'S FUCKING ANNOYING!!!!

Get the Leonard mug.
A smart-alec who uses the of cover of "quiet kid" to really suprise people when his true evil nature bursts through the top. Along with that, a harsh critic and demonic leader, capable of driving people over the edge of insanity with his hypnotic skill. Simply a genius, a vulgar, crude-mouthed, explicit, triple X and none-to-gentle genius, but a genius none-the-less.
Kid 1: Wow, that guy just nearly made those girls kill themselves!

Kid 2: He's probably a Leonard...
