When having sex with a female of quationable scruples from behind in front of a dumpster, slam her over the head with the lid of the dumpster just prior to cumming, so as to get her to tighten up.
See that nurse with the lower back tattoo, she is a dumpster fuck for sure, but I would have to finish with a rumpkepunch to make it more formal.
