mami and papi
Literally, mami (or mamí) and papi (or papí) mean "mother" and "father," but in Spanish slang, they take on a number of other meanings.
A colloquial and child’s form of the Spanish mamá, mami is “mommy” in Latin-American Spanish, especially in the Caribbean. It has also become roughly equivalent to “honey” or “baby,” not unlike slang uses of momma in English, particularly for a “hot,” self-assured woman. Mami can also be a term of endearment for a close female friend. Some also call themselves mami as a declaration of self-confidence (e.g., I look like a mamí in this dress!).
Mami has also started showing some signs of acting as a kind of Spanish-language equivalent of mom, a slang term of admiration, especially for famous people. But, be warned: if used of strangers, mami may be considered misogynistic, especially if whistled at a woman (e.g., Hey, mami!)
Papi ("daddy") also has more than one meaning: It is often used as a general term of affection for any man, whether it’s a relative or lover. Papi is also a friendly way to refer to any male associate, similar to calling a friend “dude” or “buddy"—or, if you're the rap artist Drake, it's what you call yourself.
