Scaring the crap out of people = AMAZING
true true... however also not recommended for use on my father, who swings first and asks questions later.
hahah..my dad does the same thing. he wont actually swing..but he'll make a fist and bring it back if something startles him...especially when he's sleeping. you'd think he grew up in a war torn country where they try to steal you in the middle of the night.
my dad does the slap where he smacks his other hand.
yeah, i've jumped out to scare him and had to quick dodge a punch
