Crusty Milkshake
This is the process by which a male ejaculates into the anus of an individual of nondescript gender persuasion who has been suffering from chronic herpes. Said male then proceeds to lick the aforementioned creamy man juice from the crusted orifice.
Skank: would you mind examining my rectum with your tongue, good sir?
Good Sir: Not all m'dear. I do so love a crusty milkshake with my biscuits.
