[[caption-width-right:341:Bonus... ''points'' for being at MakeOutPoint.]]
->''"Dudes! If the tent is a-rockin' don't come a-knockin'!"''
-->-- '''Charlie''' to Sam and Dean, ''Series/{{Supernatural}}'', "[[Recap/SupernaturalS08E11LARPAndTheRealGirl LARP and the Real Girl]]"

A form of SexyDiscretionShot where a vehicle or other small enclosed space is shown moving vigorously to show that its occupants are "[[UnusualEuphemism moving vigorously]]" too. (A common subversion is to then show that the vigorous activity in question [[BaitAndSwitch was not the one you were thinking of]].)

Sister trope to AutoErotica. May be used to help set the scene at MakeOutPoint. If they get particularly carried away (or the parking brake fails), may overlap with DestructoNookie.

Compare RightThroughTheWall.
