When a man with a dark handlebar mustache takes a splooge shot to the face and the white cum mixes with the mustache to appear like a suzy-q (the pastry).

Slight variation is when in the cold the cum freezes to the handlebar mustaches creating a frozen suzy-q.

Slang name for the anti-psychotic drug Quetiapine. Valued by inmates of American prisons. Up to 25% of inmates may be prescribed it.
