Bitching into someone's ear when you don't want the group to hear.
"I'm going to take a picture but I have to turn on the flash." Friend whispers bitches only to you -" Flash photography makes me look awful" Me - Please stop the whisper bitching.
Legend has it, that once upon a time there was this rat that wished it could fly. So after praying numerous times to Allah, he finally got his wings and his rat brotherin' named him bat.
