Fat-slap

The act of offering one's seat on public transport (most commonly the Subway) to a lady who appears to be pregnant but who is, as it turns out, just a bit fat.

John: Excuse me ma'am I see you are with child may I offer you my seat?

Natasha: What, bitch? Are you fat-slapping me!? I'm gonna beat yo' sorry ass!

John: Fuck off.
