forehead job 

A particularly violent form of sexual stimulation involving a girl's forehead running up and down the shaft of the penis in an effort to provide pleasure. Often results in a visit to A&E.

That Amy girl gave me a forehead job last night, I needed twelve stitches!

Foreheadjob 

When she slams lube on her forehead, and ferociously headbutts your dick.

Alex: Darling, could you please give me a foreheadjob?
Grace: Yes Alex, let me grab the lube.
