Gaiden - Gaiden is the act of sneaking up on a woman during sex, bend

Gaiden is the act of sneaking up on a woman during sex, bending over, and farting in her face. She’ll never know what hit her.

I did the gaiden to my girlfriend. She didn’t even notice.

I gaiden my mom and she yelled at me for the rest of the day.

I did the gaiden and my dad died of laughter.
