Knuckle Neckin’

When you have a stoma and that is plugged up and needs someone to shove a finger down knuckle deep to clear it out so they can breath.

Debbie, “Stan you ok?!”
Stan, “ndbbsxibdei” (mumbled but quiet)
Debbie, “He can’t breath!”
Paramedic, “move aside ma’am his stoma is plugged up, he just needs a little knuckle neckin’ “
-Knuckle Necks-
Stan, “I can breath!!”
Paramedic, “Yeah I got in there deep. Your welcome” -walks off with a boner
