What is A Cup?
One of the most perfect sizes for a girl's breasts.
'I prefer slender A cup breasts over big ugly breasts.'
The breast cup size which is of measurement A. Girls may be made fun of being "flat-chested" but actually they are the best-looking tits. Perfectly fits in your hands and very cute when you cum on them.
Friend: Dude, looks like Megan has a cup. Haha, stupid flat-chested bitch.
Me: Actually, I had her in bed with me last night. She had great tits. Small, but cute.
Friend: Wait, what? Hook me up.
The smallest cup size for a woman's breast, the actual size of the breast does not usually exceed the size of the nipple. They are nice because they won't sag as you get older or give you stretch marks, but bad because people will make fun of you for being flat and you might not get as many boyfriends.
Dick: "Michelle's pretty, but she only has an a cup."
Regina: "That's because she's a ballerina!"
A cups are the best boob size! For everyone thinking A cups are small, they are actually very big, and you are jealous because you're either flat-chested or you have like big fat saggy boobs.
Hawt Guy: Whoa, man! Check out that chick! Her boobs are huge! I'll bet she's an A cup!
Other Hawt Guy: Yeah! She's totally hawt!
The smallest breast size a girl can have. Very small boobs. Being flat chested.

Tracey got breast implants and went from size A-cup to size D-cup and was much happier. All the boys liked her then.
