When I'm at uni in Nottingham:
Cottagers, Butthole Lane, Hole in the Wall, Jughole wood, Foul End, Dirty Gutter, Willey, Butt Mound, Shatton Moor, Butty Moss...
(Arses seem to feature a lot in the East Midlands - hmmm.... Also, despite not being dirty like the rest, I think a special mention must go to Bunny - it always makes me smile
And when I'm at home in Cardiff:
Box Bush Farm, Crab Hole, Clitsome Farm, Snatch House , Bullyhole Bottom, Lickham Bottom, Penishapentre, Butt Hatch, Lusty Hill, Lord Hereford's Knob
(not that I've ever actually heard of any of them... do these places really exist?)
And finally: LOL at Toaster!
