Someone who brooms away the mess created by groomers. Your under-appreciated dad or buddy growing up who knows that you are attracted to women and criticizes you for developing a persona that would cause your dream girl to ultimately reject you for a stronger male persona. All straight men get broomed from time to time but many refuse to admit it out of the fear of appearing weak.
My buddy was mad that I was being a broomer, but I know he'll thank me later when he gets his dream girl and deletes all the groomers on his contact list holding him down.
A broomer is an excessive drug user, who will use drugs in the public if he/she wants. They will go through drastic measures for the thrill of a drug, such as crushing up T3's, or perks.
Oh my God, look at that girl, she's a total broomer!
