The male version of a cougar. A older man you would like to fuck. Now a serious bobcat is when the guy is really old but still super hot and you would bang him.
Bobcat is a word describing the little brother syndrome of ones instate "rival". When one team feels they have a rivalry with a vastly superior opponent. The superior team usually doesn't know the Bobcat (little brother) exists or is any kind of a threat. The Bobcat (little brother) usually puts forth maximum effort in meaningless situations in order to get the point across on social media or message boards.
A bobcat is usually a person who is so annoying. They would continue to keep talking about the most annoying thing ever. They often act like babies and think they can get away with everything
