look up any word, like dirty sanchez:
The act of banging your friends girlfriend on the top of a bunkbed, only to have semen drip down on your sleeping friend below. Its mean and cold heart-hearted hence "Frosty Wingman"
"After everyone passed out at the party I totally pulled a frosty wingman on shelly last night. Nick didnt seem to notice till his face got warm.
