When a Norwegian male by the name of Morten displays his acclimation to American culture by using words such as "wat?", rapping in a Norwegian accent, uses phrases such as "that's what your mom said", and flirts with American girls, even though he finds Norwegian women superior.
Ms. Perfect: I think that's hot.

Morten: That's what your mom said (heavy on the Norwegian accent, throwing a paper airplane at me)

Ms. Perfect: Stop with your Mortenisms.
