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

A guy who is flaky and never agrees to plans. He always bails out last minute. Usually is sensitive and sad underneath, and just needs some friends to stick by his side.
He is such a flake chump, he never leaves his house and always flakes out last minute. No wonder he has no friends and always listens to sad music

"The only thing worse than a one pump chump is a hump chump."
