What is Turkeying?
1.
The act of when someone goes to give you a high five, instead of slapping their hand, form a fist, stick your thumb out, and hit their open palm with the bottom of your hand (the part of your fist opposite your thumb sticking out) then proceed to wiggle your thumb while your hand is on their palm, saying "gobble gobble gobble."
Thus forming a turkey to thwart their efforts of slappin' five.
Jack: So I went to high five Matt, but he ended up turkeying me.
Megan: What a douche.
