A twidly knob is the humorous version of
male yodler (i.e. dong). Commonly mistaken for a twiddle stick, or a regular knob. The difference between a twidly knob and these other
two misconceptions is that the twidly knob is usually half if not a
quarter of the size of a twiddle stick or a knob.
1. Hey
Mum, I saw that Joel kid's twidly knob today!
2. You know what James, I'd prefer a hefty twidly knob over a pair of
juicy twidly
tits.
