B.O. 

Body odor. Some times confused with crack, and crystal meth.

I went out side, SMOKED A BAG OF METH. Then i smoked some crack after that. Came back inside, and my bitch is like, "You smell funny." I'm like, "BITCH, thats just my B.O.! And if you dont like it, i'll kill your ass..."

Bitch: I don't like her, she stinks of cheese and onion. means she can't wash.

Abbr. for Bitch Out. When someone has decided to leave early, back out on plans, pass out, or just generally be a bitch.

Where'd Kyle go? I thought he was going out with us.

No Kyle B.O.'ed, and went home.

B.O. 

Abbreviated form of Big Ox

Used in an analogous way when the person with the body odor doesn't know what B.O. stands for originally.

Ramya had a B.O. that the Axe couldn't stop while in full force.
