Mmm you can die from a punch. I've never heard of anyone dying from a slap.
And mostly, girls slap. Which doesn't happen often unless YOU do something to provoke it.
If a guy slaps me... Well... he'll be eating my punch. Slap VS Punch. Which would you rather be on the receiving end of? o.O
this isn't me, it's my girlfriend
now leave me alone muahaha
