a side of fries
when someone takes a blow job, swallows the cum, and then shoves it straight into their butt using a crazy straw
He took a blow job and drank cum through a straw. That's a side of fries.
She swallowed the cum and then shot it up her butt. Classic side of fries.
He texted me: 'I drank cum through a straw and shot it up my butt. It’s a side of fries.'
