When one does something alone because no one will go with them

Music so good it could elicit sexual arousal.

A new term for "masturbate"

A solitary journey to the heart of intoxication. Often the last (but sometimes the first) refuge of the lonely.

Usually a guy (playa or gashman) but could be a cougar on their own in a bar or club on a predatorial hunt for action.

The playa will often make up some fictious excuse as to why he or she is alone but in truth they prefer to hunt alone and often do so (in preference to using a wingman).

Refering to the military origin - solo players consider themselves as experienced assasins or ninja's in the art of the singles bar or clubland.

Going out by oneself, whether to write graffiti, steal, or whatever.
