look up any word, like smh:
Male masturbatory practice.

A spong laden with baby-oil/lotion is placed on a toilet seat; the erection is then place upon said sponge. A second similar sponge is then place atop the erection, and the toilet lid is then pressed down upon the whole caboodle. Thrusting can then commence, applying harder down-pressure as climax approaches.
I'm going home to have a good old sponging tonight!

A "Nasal Blowjob" whereby nasal mucus acts as a lubricant for a man's erect penis.

The ejaculation occurs inside the nose, or nasal pathway, before the person being "sponged" sucks it up along with mucus to the back of the throat, and swallows it.
"I totally sponged that bitch last night."

"I'm sorry - I have a throat infection. But you can sponge me all you want."

"Sponging makes me come so hard."
