A test that determines if one's future significant other (e.g., future boyfriend/girlfriend) is a keeper. This is usually done on a date by bringing the subject (e.g., future significant other) to a club where he/she is supposedly to get hit on by other suitors.
If the subject welcomes & accepts advances by other suitors and completely ignores his/her date, the subject is said to have failed the test. This test happens in both straight and gay communities; though, it's more prevalent in the latter.
Friend: So how did the club test go for your future boyfriend, Trevor?
You: He failed badly. We went to this club last Friday night, and a hot blonde started talking to us. Trevor very much welcomed the newcomer's presence to the point that he asked me to watch their drinks for a minute.
Friend: Damn, what a douche.
You: Yep. The club test surely revealed that he's a very low-quality BF material. Ain't nobody got time for that.
