Shipping name of the romantic slash pairing of Harry Potter characters Remus Lupin and Sirius Black. It is unknown whether Wolfstar is canon or not. The Wolfstar shipper delights in such phrases as 'lie low at Lupin's', 'Lupin, who was staying in the house with Sirius', and my personal favourite, 'None of us is hiding Sirius Black under our cloaks!' The 'fourty line stare' has also become incredibly famous (for fourty lines during the Order of the Phoenix, Remus does not look away from Sirius).
The name comes from the fact that Remus is a werewolf and there is a star called 'Sirius'. Other common names for this pairing are Remus/Sirius, Puppyshipping and The One True Way.
Shipper: Wolfstar are my OTP

Shipper: HE ONLY MARRIES HER AFTER SIRIUS DIES HE AND SIRIUS WERE SO TOTALLY IN LOVE IT'S THE SEXIEST THING EVER SIRIUS HAD A FLYING MOTORBIKE
Person: I'm willing to believe Sirius had a little bromance with James Potter-
Shipper: NOOOOOOO WOLFSTAR IS CANON WOLFSTAR IS BEAUTIFUL
