A way of giving your thanks, gratitude, and affection when someone does something that worth making you say thanks for. It can be used at any given time, place, situation, and setting. It could also mean to spank someone, whether they've been bad, or naughty bad.... mmmmmm. It could also be used in a gangsta form, sphanksta. It's for douche bags who's too sphanksta to say gangsta.

Joey: I don't know, I think he thinks he too spanksta, when he's just a rich white-boy douche bag that lives in Brooklyn.

Get the Sphank mug.
While two people are having hetero intercourse, Sphanking is where a 3rd party inserts their hand into the females' anus and strokes the males' penis from the inside.
I was fucking my girlfriend last night when her roommate walked in and gave me a sphanking like a vet birthing a baby calf.
