im fighting dirty .
unless a dude with a group does this, where you legitimately have to worry about his boys jumping in I'm fighting him. and I'm immediately on him no words or nothing if he has a strap on him he should have had it out before slapping her on the ass. win or lose me and wifey are skating quick and she can decide how she feels about it later.
A dude does that and it's really about testing you

nothing to do with her so you leave it alone and say lets get out of here or go all out from jump.
