Cumtucky Backfire

A sexual act involving nutting inside the vagina at the same time as she queefs, blowing the cum back all over the male’s genitals.

nostalgia backfire

An event in which someone gets re-acquainted with a favorite song, movie, or other thing from their past, but eventually finds that it only reminds them of the time at which they got back into it.

My junior year of high school, I went up into the attic and found that Super Mario game I used to play when I was, like, 10 years old. But now when I play it all I can think of is how it was the one thing about my high school days that didn't suck. What a total freaking nostalgia backfire.

backfire

The moment where, when you're taking a shit, a large pocket of gas (referred to as a future-fart) that was resting mid-shit or between two shits escapes as you're passing your lovelog, resulting in a sudden violent fart than not only propels your previously freefalling turd at Mach 2 speeds, but also results in a pleasing shotgun blast of turdlings across the toilet bowl.

A backfire is so named for it's similarity to a car backfiring.

"Man, I was taking a dump and backfired, and now I get 'Nam flashbacks when I visit the shitter."
