A shaqueef is a combination of a Shart (shit while you fart) and a Queef (a vaginal fart).
Cheyenne just Shaqueefed all over Bella in Study Hall today.
To shart (A shit-fart) out of a vagina. This may come in the form of drops, spray, or diarrhea.
Man, last night Gail and I were going to town in the bed, and she up and shaqueeved up in my grill.
Dammit mom, I thought it was my period, but in fact I had a shaqueef!
