Wadena Butterfinger

Buttering 4 of your fingers up her #1 and #2 holes while getting BJ. When ready to blow, shove fingers under her nose and say something salient to Minnesota.

Ex: "This ain't Minneapolis sweetie" Or, "Did you know Harmon Killabrew liked bj's too?"

I met this chick from Minneapolis at the NiteOwl, she was talking shit all night. I had to give her the tourist treatment

Did mean the "Wadena Butterfinger" ?

Yep.
