Thirsty, thirsty, tryna choose
I mean, I know I'm pretty cool

from Chance The Rapper (Ft. Kembe X) – JUICE Lyrics on Rap Genius

Meaning

Thirsty is often used to describe someone who won’t leave another person alone or who acts very energetic and proactive at obtaining them. Since these girls are all over chance all he has to do is choose. OR the girls are the ones “tryna choose”. When an individual is visibly attracted to another it is common to say that they are “choosey”, slang for enticed.

It can also be said that people are “thirsty” for new, good music and are always trying to determine their new favorite artist. Chance says try his Juice cause he knows his music is pretty cool.
