Dua Lipa uses "sugarboo" in her Levitating song. What does it mean? It seems to be in no dictionaries.
Some lyrics to that song are:
You want me, I want you, baby
My sugarboo, I'm levitating
The milky way, we're renegading
(Yeah, yeah, yeah, yeah, yeah)
This is a slang combination of boo and sugar, both terms which indicate someone you care about in a romantic way -- lover, girlfriend/boyfriend, etc. This means the same thing.
