Eating while one sits upon the toilet and shits, thus expelling the old(shit), and ushering in the new(food). Hence, we get the old saying, "Out with the old, in with the new".

Where have you been? Out with the old, in with new, bro! Shit while you eat, but remember not to shit where you eat.

WTF mate!
