acquired immune (or immuno-)deficiency syndrome: a condition, caused by a virus, in which certain white blood cells (lymphocytes) are destroyed, resulting in loss of the body's ability to protect itself against disease. Merm-Aids is transmitted by sexual intercourse, through infected blood and blood products, and through the placenta. Gay Mermen are at high risk of contracting Merm-Aids. The first known case of Merm-Aids was documented in 2005 when Ray William Johnson stuck his dick in a Blowfish. We'll miss you hootie
Don't touch Ray William Johnson, he has Merm-aids. Maybe Elton John will write a song about it.

A chick who is a hot babe from the waist up, but fishy from the waist down.
After taking that babe home from the bar last night, I discovered she was total mermaid, cause her snatch was sour but she looked hot.
