white banshee
A term for a woman pleasuring a man by way of blow job and the man delivers a passionate karate chop the woman whilst screaming “White Banshee!” as he’s cumming in her mouth, forcing his jizz to explode from her nostrils. Leaving her looking like she’s got creamy white snotcicles.
“Dude, I totally white bansheed Karen last night.”

“No way! What did she do?”

“Flipped a shit and left… Which was perfect cuz I wasn’t planning on calling her again.”
