What is Tits'n'ass?
1.
First born in Scarborough, Ontario. A form of a traditional clinking of beer bottles as one would say "Cheers". First the involved parties clink together the tops of their beer bottles and announce "Tits!", following closely is the clinking of the bottom of the bottles together announced "and Ass!".
"Jay and Alex got drunk doing Tits'n'Ass cheers all afternoon long."
