Stands for Ecstacy and Oxycodone.
"Initiation" - The Weeknd
...Baby get familiar with the order
Just crack it, then pour it, then sip slow, then tip low
My eyes red but my brim low, that XO, she climbing
Straight to the top, forget why she there in the first place
No more crying, heart rate's low, put that rum down you don't wanna die tonight...
"You better get your 4187 signed by the commander before he goes on leave otherwise you'll have to play 20 questions with the XO when he is the acting commander"
