A person who feels as though they have to flirt or whore around with every member of the oppsite sex on the bus to make themsleves feel important. The Bus Whore will probably end up dating multiple people on the bus and will have very big commitment problems with them. He will probably end up going out with them for a week or so and break up with them out of boredom and then move on to his next victim.
"Hey Lulu look at that douche whose going out with the bus whore." " Wow Brando what an idoit , there only gonna be together until that manwhore gets bored"
