The act of receiving head while shitting-except instead of shitting in a toilet you shit into a jack 'o' lantern. Most often occurs around Halloween
Dude I ain't gay or nothing, but that 11 year old boy dressed as Frodo just gave me a wicked grump 'o' lantern. Good old Jack now has a shit eating grin-literally. Happy Halloween!
