The dirty hydro skimmer is when your girl is in the tub and is taking a bath. After she not only cums but defecates in the water she pulls her bottom half out so her vag is half way out. The guy gets in the tub and licks the girls vag and inserts his tung into her vag as it is under the water and gets no only her cum but also piss and shit in his mouth. He will do this tell she cums and there share a cup of her dirty bathwater.

A safety device that is used after spooging in hot-tub, pool, etc., and the spooger has the skimmer to get rid of the evidence prior to another using the water works.

Any insult that you would call a person. Has multiple meanings. Could be a Gen Z loser. A scaredy cat. An idiot. Any insult you can think of to describe a person.
