Gutter helmet 

A regional variant common to southern New England for the practical joke/sexual practice known elsewhere as the Dutch oven: i.e. when one partner holds another partner's head beneath a blanket and passes gas.

Sheets are OK for a gutter helmet, but for the real, face-full-of-flatulence effect, you need to go with a down comforter.

Gutter Helmut

The art of ejaculating on that one spot, towards the back of her head, where it causes a flow down to her back and then continues along her ass crack and ends up collecting into a pool on the floor.

Damnit Cletus! Why you always gotta jizz on the back of my head?
Listen here woman! The day you can jizz on the back of my head is the day you can tell me where i should be jizz'n!
I like how it just flows like rain...
Now go take your shower and let's cuddle, my little gutter helmut!
