Snowman's 'Tache

After the male has expelled the majority of his semen in what ever manner he deems fit the remaining load is squeezed out along the top lip of the recipient, giving them a creamy mustache like that of a snowman.

Inspired by milk promoting posters typically found on the sides of buses and starring Rupert Grint (Ron Weasley)

"Gave the wife a right snowman's 'tache last night, she looked like she'd been guzzling a pint of milk!"
