A guy masquerading as a girl on the internet or a game for attention or benefits. This was derived from the real life equivalent of a guy pushing his manhood in-between his legs so as to look like a woman from the front. The tail in this example is of course the penis.

a mermaid tail is a tail of a mermaid, though some people (typically texans) refer to themselves as a mermaid tail or having possession of a mermaid tail. those with a mermaid tail, seem to be slightly or overly phsychotic.

Bologna tail is the result of either lifting to much weight when squatting or pushing when pooping, causing the inner lining of your colon pushes out creating the illusion of a pink stinky tube tail.
My Doctor always warned me not to push when I was on the toilet...but I was in a hurry trying to get back to my Dancing with the Stars Marathon and.....PLOP....I now have a bologna tail.
