Booty check
That patented move that girls (and some guys) do in front of a mirror to see how good their ass looks in the jeans they are trying on. Involves craning neck backwards while pivoting on one's toe.
I felt like the dutiful boyfriend while she did repeated booty checks in the mirror at H&M.
Booty check
when a nigga is doesn't get any because of an random interference.
'That nigga just got Booty checked"
