Another word for "Thanks" , usually said by teenage girls . Shpanks is just a more fun/cool way of saying "Thanks" .

A cross between, or combined use of, shanking and spanking. Usually performed during or after a sexual encounter; in most cases by accident, however, some are out of anger or disappointment at a preceding exchange of sex that just occurred and left one or both participants unhappy and unsatisfied. A person may shpank their partner by spanking them with the sharp end of a knife, thus stabbing them in the butt, and leaving for an incredibly awkward and painful night. A shpank can also be performed on accident by an attempted shanking that missed, due to confusion of butt location due to saggy pants.

Stupid way to say the word spank, which means to beat someone up. This is one of the 4 main words that people say with a Sh sound instead of a S sound, for no apparent reason.
