Christian was very hateful on the phone with the nurse, so she yelled "Dont back-mouth me!" and hung up on him.

Get the chirp backmug. In alpine skiing, being in a position where one's center-of-mass is shifted toward the tails of the skis instead of toward the tips. Results in reduced control, adaptability to changing terrain, and ability to make a full turn.

Get the swallow backmug. The arch in some chick's backs when standing, showing off their ass. The chick's back curves like a Banana, making her ass appear to be more pronounced than without a Banana Back.
A: Hey, Katie has a nice Banana Back! I could stare at that all day!
B: Yeah, I know! that ass is seductive!
B: Yeah, I know! that ass is seductive!
