Feacal matter wise - you can control the food volume you consume during the day (many stick to liquid diets during the day, with a heavy meal at night once the anal work is done).    Prior to the big even you also can have a wash out of ur arse, and get rid of any feaces lingering up there. The problem is you have 1-2 hour window before my feaces can then enter that region (if eg, you had a big meal and were pushing food down).    It's not easy. It's why most sexually active ladyboys are thin. 

My mum serves Christmas pud as a slice. Proper old-school-boiled-for-six-hours Irish Christmas pud.
It's probably slightly angled, because the pud is round. You're not after big wedges though so slice it thin, because it's quite a solid dessert. 
Bit of cream, or for me ice -cream on top, yes please may I have another!

So is mine when I have a BBQ.

the pepper steak at Buddy's bar is excellent
