Literally means "Drink my cum".
It was created in 2018 by a reddit user who goes by u/ThirstyMudkip and he then changed it as his name on Instagram.
He's an eboy, trashy guy who wears unbranded clothes, except for his Puma.
He's got ugly ass hair and if you find any "SipOnMy..." it's 100% one of his accounts
Boy: You should Siponmysauce
Girl: You just don't drink sauce like that...
Boy: My cum, you idiot.
