A sexual act between two homosexual men, wherein the penetrative partner ejaculates onto and around the anal opening of the receptive partner following an extended period of vigorous coitus. The penetrative partner then proceeds to grasp the flanks of the receptive partner and squeeze his buttocks together, causing the amassed semen to exude through the narrow gap, whereby it is collected on the head of the penetrative partner's penis and fed to the receptive partner.
When my man is extra hungry, I make sure there's a Sloppy Justin on the menu.
