Originated at the Cal Poly San Luis Obispo campus. It is a marker in the shape of a blue hand used to deignate where a male has been sexually assaulted or raped. By rape we mean being actually raped or completely owned, ie: bad test grades and prostate exams. see "owned"
Why is there a Blue Hand on Captain Mike's door?, He definitely deserved a bluehand for that score on his math test., Chris molested Matt last night during the movie, hence the blue hand painted on the carpet. Mitch and Geoff bluehand at everything.
