Jack Knuckles
A guy who lives to fap. He's always on his phone looking at stupid pics. He's a total waste of oxygen and smells like old cheese.
'Jack Knuckles is in the bathroom again. I swear he faps louder than the school bell.'
'He's been watching porn since 8 a. m. He's like a robot.'
'Jack Knuckles just sent me a picture of his junk. I'm never talking to him again.'
