Football QB metaphor applied to dating meaning to get told by someone that they just want to be friends or don't like you back, before you can make a move or ask them out.

In football, when a QB gets tackled before he can leave the pocket created by his linemen, it's called getting sacked in the pocket.
Me: Yo man did you ask that chick from your class out yet ?
Tom: Nah, man I got sacked in the pocket.
