spidergasm 

The sudden rush of aggravation and disorientation felt when becoming ensnared in a previously unnoticed spider web, often accompanied by random thrashing movements. The intensity of a spidergasm may be heightened if the subject is not fully awake or suffers from arachnophobia. A secondary effect may be felt up to an hour later if the spider responsible for the web is found in the subject's hair or clothing.

Chuck lapsed into an uncontrollable spidergasm as his face brushed against a web as he exited his house.

shergasm 

A term to describe an unexplainable sense of warm fuzzies one encounters when talking or even thinking about people named "Sher" or "Cher".

Often, a naked recorder-playing fairy will come out a fat lady's vagina on Jerry Springer and serenade you with Blue October songs when this is happening.

Also, most people experience loose bowels and spontaneous urination.

Ohhhhh! I'm having a shergasm! Here comes the naked fairy!
Lmfao Story for you!
