What is Defrosted?
1.
a person who's a loser one year of school, summer passes and all of a sudden is the coolest/sexiest person at school.
this mostly occurs in high school.
Person 1: hey dude, you hear about that girl, Liz?
Person 2: yea man. junior year, she was a total nerd and no one knew her. i guess she defrosted over the summer, because this year... every dude wants her.
