I told her I couldn't take her home with me because that street meat was sitting right but she offered to give me a Thai Blumpkin.

A blumpkin received at a Dunkin' Doughnuts establishment. Only after buying an unfrosted doughnut and placing your penis through the doughnut hole may the blumpkin begin. The Dunkin' Blumpkin is only completed after you have frosted the doughnut yourself and it is finished by your partner.
