How to Drink Tequila Like a Man

1 bottle of tequila
1 bowl of sliced lime
1 small plate of salt (optional)

Drink tequila from bottle.  Pass bottle to your friend.  Suck on lime as your friend drinks from bottle.  Do not pass the same lime to friend.  Instead, pass bowl of fresh lime to friend.  The juice from the lime will help disinfect the bottle when it’s your turn again to drink from it.  The optional salt is there in case all the juice in the lime is gone.  Repeat until bottle is empty.  Open up new bottle.

Tip:  Ditch expensive tequilas like Herradura Seleccion Suprema, which costs about $320/bottle.  It's considered ultra-anejo, which evidently means it has been sitting on the store shelf for more than 5 years because nobody wanted it.  I recommend cheap tequila.  Generic or moon-shined is also good.
