Gentleman's B 

When you have a good enough grade in your class and you are so bogged down by other work at the end of the semester that you email your professor and tell him you're not gonna take the exam and will take a "B" in his class

Student in email: "Dear Professor, my finals period is packed and its just not worth it for me to not sleep for the next three days to get a good grade on the test since I have a really good grade in the class already. Can I just take the Gentleman's B?
Teacher: Sure.

Gentleman's Bird Bath 

Any Gentleman standing on his tip-toes washing his tallywacker off in the sink after anal sex. Usually performed because the female half will not allow re-entry into her vagina without a thorough scrub.

A.J. - "Everything was going well until she made me take a Gentleman's Bird Bath mid-romp. It killed my Woody Wilson."

Gentleman's Bet 

A wager on principle rather than for significant amounts of money.

A typical Gentleman's Bet will be for no money or a nominal sum (e.g., $1) with the "prize" of being correct going to the winner. Think of Trading Places and the bet the Duke brothers made.

Gentleman’s Bridle 

Fishhooking your index fingers inside both sides of her mouth while you take her to pound town from behind.

After deploying the gentleman’s bridle, I clapped her cheeks and steered her around the house. Eventually made to the kitchen for a beer before I blew her back out.
