I'm in a similar situation.
This little friend hangs around with us all the time now; he's my best friend's brother and if this kid can't hang out with us then neither can my best friend (according to his parents). This kid's like, 12, and he acts like he loving owns the lot.
tl;dr Everyone has to hang out with this little forgetprick around our neighborhood or else he leaves and we all get in stuff. >:c
Example: We were all playing football and Brandon (The prick) gets jersey'd. He was laughing and grabbing at his stomach and people started saying "Yeah, grab that skin Brandon!" and I blurted out "Get a hold of that cellulite!"
So he says "forget you mack, you're no better. loving bitch, you've got tit's bigger than my mom."
I respond with "Then your you must not have been breastfed if your mother had that small of tits!"
Crowd goes "OHHHHH stuff"
peh, later on that day I clocked him in the side of the head pretty hard and almost lost a best friend but oh well.
