look up any word, like tribbing:
 
1.
v. To laugh or chuckle during a sexual act, preferably the sexual act of fucking.
"So I was banging my old lady last night, and she made this funny noise and then said, 'oh fuck me hard big boy.' So then I fuckle chuckled right in her face."

"When the vagina farts during sex, I can't help but fuckle chuckle."
