Scanger perplexity

This is the confused facial expression of scumbags. Many reach it by default rather than by design and it firstly involves a tilting of the head by 20 degrees. Meanwhile the Mouth opens like guppy fish at feeding time. A furrowed brow below a greasy mop of hair completes the package. Many accompany this look with a matching tracksuit and Nike runners.

Conductor: "sir you can't smoke on this bus"
(Scanger begins the look - scanger perplexity)
Scanger: "eh warewil I fuckin smoke den?!"

Or

"Hey look at that scanger perplexity on that toe rag reading the bus timetable"
