Cricket

Played in backyards throughout the Commonwealth (English one - Australia, England, New Zealand, India, West Indies, South Africa, Pakistan, Sri Lanka, etc) this would be perfect.

Assuming you're in the US, this has the advantage of:
a) no one knowing the game (and hence, no one being awesome at it)
b) an interesting experience
c) a game that you can play while holding a beer
d) not too fast
e) not contact/physical
f) in backyards across Australia/India/etc. you can typically get the equipment for around $10-$30 or so - a tennis ball, something rectangular for wickets, and a bat.
