When a person straps a dildo to their head and fucks someone with it, pretty much headbutting the other person.
My cooch hurts so much from Alex's strap head.

Strap Head is when two women (usually lesbian or bi-sexual) use a strap-on to simulate fellatio. One woman wears the strap-on and another sucks on it, simulating a blowjob.
Jenny and Alice got the strap-on all wet when Alice gave Jenny strap head.
