This is a slightly generic term for the supreme God of that fiery drink PULQUE. It usually refers to TEPOZTECATL, but sometimes it doesn’t. Especially when he’s had a few too many and needs to lie down for a bit.
’OMETOTCHTLI’ means ‘Two Rabbit. No mention is ever made of ‘One Rabbit’, but they were probably all seeing double by then anyway. See CENTZON-TOTOCHTIN.
