A Bon Jovi
Seeing someone from behind with tight jeans and long hair, only to realize it’s a guy when you see his face like it’s a surprise.
'I thought it was my crush, but it was my brother wearing my crush’s clothes.'
'I saw a hot girl from behind, only to find out it was my dad wearing my mom’s clothes.'
'I was about to flirt, but it was just my cousin trying to be cool.'
