wachove
To agree with a significant other to be exclusive, but with no intention of honoring that agreement at all. This term is based on Wachovia's exclusivity agreement with Citigroup, which was made while Wachovia was better-dealing Citigroup with Wells Fargo.
She told me she either wanted to date exclusively or not at all, so I decided to wachove her. Now I'll have to be more careful with these other girls.
