A common bet done in Middle school or High school when idiot men do a little of manly toughness when getting the affections of really pretty girls. For example, a commmon gentlemen's bet sounds like:

Hey i bet i can get her number before you can.
other guy: You're on!Lets start this gentleman's bet
