When someone spazzes out when riding on a bus, causing them to orgasm.

When a person (you know who you are) over exagerates their actions in order to get attention from their peers. For example, apon being shot with a mere 0.12 jule BB gun that person could scream out in pain and run away before returning only to be shot multipul times for a derranged form of pleasure.
People like this are also known as wordfucktardsword.

Spam advertising images that appear on web sites and undergo jittery motions in order to catch one's attention.

A surprise orgasm !

A spewing orgasm. Women who are capable of achieving this feat tend to hide this from their boyfriend until they get the chance to blow a load all over his face in retaliation for all of the clogged nostrils and sticky hair women have had to endure throughout the centuries.

When an old geezer dances. It isn't lethal, but it results in embarrassment and overstimulation.
