When you get jumped from behind by a chump who wasn't brave enough (or good) enough to square up to you. So they gotta be a chump and jump you so you have no warning or defense.
CHUMP-JUMP
CHUMP-JUMP
There's no warning or defense when you get chump-jumped from behind, that's what makes them a chump. Next time square up CHUMP if you want a W.

When you are an active Instagram follower and like everyone’s picture, but the favor is never returned and you end up with little likes and many ghost followers
I feel like such an Instagram chump when I am consistently liking all of my followers pictures but they never like any of my pictures!

I cheated on him twice, then told him it was okay and it won’t happen again, and this chump actually listened to me. But you know on the low I still cheat. I told this chump if he doesn’t stop talking to his friends, I’m gonna leave him. Now he has no friends. What a chump.
