L Stand Blumpkin
When someone gives you a blumpkin from doing a L stand, you're the one who got stood up like a doofus.
You tell your friend you're going to the mall. He says: 'I'm doing a L stand.'
You text your crush: 'We're going to the concert.' He says: 'Nope. I'm doing a L stand.'
You walk into class and the whole group laughs. Someone says: 'He did a L stand on you.'
