fuckable minor

This term is for someone who is between the age 18-20, since they are above the age of consent so they’re legally “fuckable” but they aren’t still treated as full adults since they cannot drink, smoke, gamble, or do other adult activities.

How old is she she doesn’t look like she’s below 19?
Don’t worry bro she’s a fuckable minor, she just turned 20 last week. Still can’t rent a car though :(
