What bro hasn't had a drunken sexual encounter, where no matter how said bro tries, they're too fucked up to make shit work. That is softserve.- A more acceptable, and encompassing synonym for whiskey dick.
Bro 1: Dude, I heard you hooked up with that girl from the party, how was it?
Bro 2: Shitty man, after I shotgunned that 4loko, I couldn't get my mind right. She was hot, and I wanted to get hard, but it was total softserve.
