when a girl, who doesn't like to taste cum or mess up her sheets when giving head, removes her own sock and places it condom-style on your dick when you say "Now", thus ejaculating into a warm cotton sock. Afterward, you make her put the sock back on with either shoes or slippers and walk around.
Dude, last night I gave this chick the best Pittsburgh Slipper of all time. Shes never getting that sock off.
