The disgusting (or highly-amusing, depending on your tastes in humor) act of farting while having missionary-style sex; it occurs when the person who's "on top" breaks wind and thus sends a "strong breeze" of gas whooshing out past the dampened thighs of the person on the bottom. Depending on how hot/chilly said "blast from the past" happens to be --- and on how temperature-sensitive the other person's upper-leg skin happens to be --- you may receive a howl of protest from said whizzpopper's "recipient", since many people hate the feel of "drafts" on their bare legs.
Depending on the condition/behavior of the lovers' digestive systems --- and whether they partook of baked beans and/or stewed cabbage shortly beforehand --- one or both of them may have "lots of traffic on the overpass" --- i.e., a frequent explanation of putrid methane while they're lustily "having at it" and thus vigorously flexing their entire groin-area anyway. Extra points if (1) you are able to skillfully "time your toots" so that they occur at precisely-regular intervals to coincide with your thrusting "rhythm", and/or (2) on occasions when both of you are passing gas while "getting it on", you practice standard "courtesy-merging on the freeway" --- i.e., you each "take turns" farting so that one of you (usually the guy, since it's easier for him to tense his abdominal muscles during his forward thrust) releases your "perfume" on each "inward" stroke, and the other person "lets fly" on the "outward" motion, so that your "collective" farts are "synchronized" and evenly spaced from each other, similar to two lines of cars alternately merging on adjacent highway-lanes like the opposing teeth of a zipper.

When a guy is having sex with a girl in a car, he hits her in the back of the head and knocks her out. He then takes a shit in the car, puts on the emergency flashers, lights the emergency flares outside of the car, and runs behind a boulder and watches for people to stop and see the utter shame within the parked automobile, all the while laughing like an excited school girl.
I pulled off an amazing Iowa overpass last weekend in my girlfriend's '85 Ford Toyota, which has 1200 pounds of torque with each sensual thrust of the piston.

However, the trial for assault and emotional damages will surely ruin me.
