Dry Hammer 

When a man surprises his partner with sudden penetration with no foreplay. Sometimes painful but always enjoyable.

I had a huge morning wood and there she was, so I Dry Hammered her while she was asleep.

Dryhummer

Dryhummer is an act of oral sex between two sex partners, hetero or homo, where the penis is inserted into a mouth unproperly lubricated or a lack of sufficient saliva, leaving the penis raw, chaffed, and sometimes bleeding.

Dang that was one dryhummer. It nearly rubbed the skin off my wanker!
