Bootylicious is playful slang for extremely attractive, tasty, or enjoyable — the kind of praise that grins. It was mashed together from booty and delicious, and a famous pop song in the early 2000s taught the world the word. Booty here is the informal word for a person’s behind (itself a playful form tied to bottom); delicious is the “tastes wonderful” word, from Latin deliciae, delights and pleasures. Put them together and you get a cheeky, over-the-top compliment, most often about a body, sometimes stretched to a song, a dance, a dessert, anything that feels ridiculously good. It is very informal, a bit dated and jokey now, and it can sound as if you are looking at someone’s body rather than speaking to the person. Friends might laugh and use it; a school essay, a teacher, or a parent is the wrong room. Not rude in the harshest way, but not polite either.

超正、超辣（早期 2000 年代流行的玩味口語，誇張地說人或事物很吸引人、很過癮；不登大雅）
