Etymology..
Actually, it's surprisingly close to accurate, "dangle" appears to be Danish, and "twat" seems to be connected to old english "thwaite", a common word in the viking ravaged areas of NE England.
However I also suspect it may have something to do with Englethwaite in Cumbria. The hills of the area being renowned for the plethora of danglers from the various rocky outcrops.
