Tootgasm 

When one lets flatus expel from the anus in the middle of sexual orgasm. In other words, a toot slip in the peak of sex. This may result in never having intercourse with that person again.

My good sir, did you just tootgasm?

Man, last night, Kyle had such a big tootgasm, a dank cloud of stank formed right over the bed.

Tollgasm 

Tollgasm is the orgasmic feeling you get while driving on rough or rugged toll roads.

While driving his F-250, the cowboy has a Tollgasm on an Oklahoma toll road.
