It is actually a term used to make fun of how Germans speak english.
"Zee" is the inability of Germans to enunciate the 'th'.
Hans-Dieter: "Zee Lederhosen were so tight JA, I could not feel zee schnitzel รยคnymore!"
Klaus:"Scheiss mich an, du Sau!"
Trevor: "Did you hear what Zee Germans said?!
Mike: They are not German, they're frickin' idiots!!!"
