fail goggles
When a guy/girl fails at getting action or maintaining a relationship with a person, he/she won't find others as attractive as said person. The strength/length of fail goggles is dependent upon time and emotional attachment.
Guy - "I just don't find her that attractive."
Friend - "Dude, you just broke up, so you have the fail goggles on. She's a 10 and I know you'd normally agree with me."
