Sinkie

The act of washing one's genetallia in the wash basin. usually done when there is no time to shower, pre or post coitus.
seen sometimes as an emergency wash.

The wife came home early last night. had to have a quick sinkie so she couldn't taste the babysitter.

woke up next to a total ugly random this morning. i was so disgusted that i had a quick sinkie, got dressed, made my excuses and left.
