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.
