Being born and bred in Doncaster (known locally as Donny), I understand all that they are saying. In fact they haven't even covered half of it.
Try these:
Isezitintisburritiz.
Wivgorragerrusimbux.
Midadzgorrajag.

All 3 are complete sentences and generally speaking anyone living over 30 miles from the area will not understand it.
