Rigor-coitus

The act of making love to a long lost love or spouse after they have died. Possibly in a scenic setting like in front of a fireplace or at a grave yard. This is not to be confused with necrophilia because it embodies the love that one may have once had for said corpse.

Walter: Where were you last night Howard?

Howard: I was just really depressed thinking about Emma's passing, i had to go down to the cemetary and have her one last time...

Walter: Sometimes rigor-coitus is the only way to relive the passion you once had, I'm sorry Howard, one day soon you'll be able to join her again...

Howard: Yea, i was thinking next tuesday possibly.

Sinus and Coitus

Sinus and Coitus are two very important functions in mathematics. The derivative (which gives the slope of a function at the point) of sinus is coitus. And the derivative of coitus is coitus interruptus, because you need to interrupt the function to measure its slope. Usually people will look at you really weird when you use those terms, because they are not used such high mathematics.

Person 1: Mathematics homeworks was really hard last night. The sinus and coitus excercises were kind of tricky, but coitus interruptus? Nah man. I went to sleep early and decided to finish coitus interruptus later
Person 2: wtf?
