The process of cumming in one's own mother, then pulling out, adding in ice cream and said mom's out breast milk, and fucking until the mixture is sufficiently stirred. A staple of family gatherings.
Nadia: I heard your mom just turned 50, how was the party?
Nate: Yeah, the party was really fun, we had a big cake, and I gave her an Alabama Milkshake!
Nadia: Nice!
