Usually used as the first or last part of an insult, "Bitch Ass" is usually the slang term of "Bitch" and "Asshole", or, as a second slang term, it can be used to describe a person as a Bitch's Ass.

The word originates from prison slang, in which it was used to describe an inmates bitch.

someone who gets on your nerves badly

Someone who cannot hold their anger in, or is very crude.

Someone/something who is afraid to do something. A real pain in the ass. They don't like taking chances and to just go for it. People/things who swim up stream and can't just go with the flow.

to basically be a pussy, to be a bitch.. umm to bac out on something or not be down(:

1.) (noun) A game in which one party calls another party "bitchass," therefor effecitvely dubbing them "bitchass" for the day. The rules (decreed by one sir God/Nicholas Cage) are longstanding and are as follows:

1. The game resets every night at 12
2. Upon becoming "bitchassed," until the game resets, when anyone says to you "Hey bitch," you must respond with a woeful "Yeah, I'm a bitch..."
3. You cannot bitchass someone who has bitchassed you until the game resets.
4. Timestamp trumps all ; if one receives a message at 1:10pm, yet they haven't actually seen the message, the bitchassing is still effective due to the timestamp.
5. If a simultaneous bitchassing occurs (i.e., two patries bitchass eachother at the exact same time), OR, if a legitamate dispute arises over who bitchassed who, a grace period begins for a time of 2 hours, at the end of which, either party can bitchass the other.
6. Thou shalt not bitchass the wild.

2.) (verb) to effectively "bitcasss" someone.

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.
