bottomizer means: 1. A top that sees bottoms as only sexual objects in gay relationships. A womanizer is a similar term to one used in straight relationships. 2. Top who is promiscuous with many bottoms and does not care about the bottoms’ feelings. 3. Unrespectful and uncaring tops who don’t know how it feels to just hammer it in, without properly lubricating it. (in Community Dictionary, added by Kenna Hughes)
