Conversation between computer geeks interrupted by an interjection by a man from Hong Kong prompted one individual to proclaim "Yeah, yeah bandwidth." The foreign man interpreted this as "you bandwidth", and now it is used in place of any form of expletive or other undesireable word that one wishes. The two words are spoken like they are one.
"Dude, you just you bandwidthed all over my shoes!"
"I would appreciate it if you and your girlfriend didn't you bandwith on my bed when I'm not in the room."
