When having sex in the missionary style you grab a girl behind her knees and push them up beside her head. This causes her to look like a moose with horns.
She wanted it deeper so I gave her the moose horns.

after some chick gives you head and prepares to swallow the load you punch her in the side while she is swallowing and then it should come out of her nose.
