v. When someone convinces someone else not to give you a gift, especially when you did, in fact, want a gift; similar to jock block
Your mom: Oh, he doesn't need a gift. Save your money, buy yourself something nice. He would want it.

Gifter: Ok, if you're sure...

You (quietly): Oh... I've been gift blocked...
