C.O.B

Crazy Old Bat. A crazy old bat is an ugly old person who gets on your nerves, and a person that is very stupid and confused

That C.O.B is such a hobknocker because she is selling weed on the free way!

C.O.B.

Continuous Open Bidding (COB) is an informal, flexible recruitment process used by Inter-Fraternity Council (IFC) and Inter-Sorority Council (ISC) chapters, often following formal recruitment. Unlike formal rush, COB allows fraternities to extend bids at any time, providing a less structured opportunity to recruit new members to the IFC-governed fraternities.

Our newest pledge got C.O.B. bid since he wasn't part of rush.
