Pigback 

The use of a pig as an unorthodox method of transport made famous by the working classes of Great Britain. Often riding to and from the pub 'two-a-pig' has made the mobile pig's back a common place for coitus.

Steve: Who's that bumhummit over there?
Bo-vice: That's Paul......his parents are heavy drinkers.
Steve: Oh, is that the guy whose parents conceived him whilst pigback?
Bo-vice: Yeah
Steve: Jesus, you think they could have at least pulled over.

pissback 

The small yet numerous particles of urine that are reflected back at you when you pee into a urinal/toilet bowl. This phenomena usually happens when too much force is exerted when trying to force the urine out, causing the pee to have such a high velocity that when it strikes the surface (either water or porcelian) it instantly atomizes and reflects back toward the direction where it originated from.

There's all this pissback on the floor by your toilet man, clean that up.
