I see it all the time on ebay, N/R after the name of the racquet. What does it mean? Not real? Lol.

in auctions, NR would normally stand for "No Reserve"

That's a good one :) (Not Real, lol)

in auctions, NR would normally stand for "No Reserve"
and just to add on this (incase you don't already know), no reserve simply means that the seller has no minimum sell-price, and whatever the auction ends at, will be the legally binding sale price.

of course, the seller still has his right of revoking the auction seconds before it ends at the undesirable or unacceptable price. :(
