Or has had the dumb shit done to them.

True. Probably both.

I've said it before in this comment section and I'll say it again- everyone has a relationship dynamic. I don't think the lady in the tweet did it to purposely upset / anger her boyfriend when she said "fuck with". We don't know what their relationship is like. Some people prank each other to no end, and some people also would despise it, and find it incredibly immature because they don't enjoy that. And both of those things are fine. 

 I would probably be fine with a good prank, but if I found out when I was angry? It would just annoy me, rather than make me laugh. Just- don't fucking bite all of my donuts.
