1.) n. 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 typical female and is therefore entitled to bitch)
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.
"Man, I really hate hanging out with Nikki when her husbands around. He's always such a bitch ass!"
To a male:
"You want to barrow a tampon, bitch ass?"
