When someone in a heterosexual relationship decides that they no longer want to be in their relationship and look for a quick escape by claiming they just realized they are gay.
(Conveniently Gay Female to Long-Term Male Companion): I'm sorry, but I just don't think we can keep seeing each other.
(Male Companion): What? The wedding is next week, did I do something wrong?
(Conveniently Gay Female): No, my best friend just helped me realize that I am actually gay.
(Male Companion): That sucks...
