fish tanking 

When two people are making out intensely enough and for such a duration that they make a considerable amount of noise.

This often irritates the unlucky individuals around them, who must either tolerate the noise or awkwardly tell them to "shut the fuck up".

Girl: "Hey, I totally know about how you you two were hooking up in the closet last weekend."

Guy: "How'd you find out?"

Girl: "Because you two were totally fish tanking!"

dry tanking 

taking a crap in the toilet tank of a person you hate, preferably at a large party. the owner of said tank, upon sniffing the crap, will flush to no end until they realize they are flushing the unflushable.
