BEEP is a high-pitched note that's used on TV and such to censor offensive languages.
"oh, i forgot my bag. beep it!" > fuck it
"it's friday and we've got H/W? beep that!" > fuck that
"oh that beeping bitch!" > fucking bitch
"it's all beeped up!" > fucked up
"what the beep?" > what the fuck
Derived from the word 'beep', used to describe a woman who is so fat that she resembles a bus, and when she backs up, it is possible to honk and horn and people will think it's a legit bus backing up. The term was found online one late night in Amy's kitchen, after learning the soulja boy dance. Contrary to the definition, none of the three girls are extremely large and/or resemble large methods of transportation. In fact, they're pretty damn hot.
