one who likes to yell as if they are tough but when someone gets serious back at them they become a pussy.

Popular name for the University of Maryland mascot Testudo. Originated from a rumor that rubbing a stature of the mascot would bring good luck. After this ritual brought many students misfortune, the name Bitchass was chosen in reference.

A useless person, most commonly male, who whines like a bitch every time something doesn't go their way. (Not to be confused with a Bitch who is just a female that acts the same)

2.) A person, who has a negative, often unwarranted opinion about anything or everything presented to them.

3.) A guy who is such a pussy even girls bust his balls (assuming he has any, doubtful.)

Defining features of a bitch ass are feelings of self entitlement, inability to cope with daily life, pathetic attemps to gain others sympathy, constantly dwelling on negative thoughts, and the amazing ability to bring down everyone around them.
