Lots of people have this achievement, you must sniff no-no, then watch your buff. When you start with the crash buff sniff again, rinse and repeat. In no time you too will have the dragon chaser badge... but beware... you should just say no to no-no :P
It's very easy, you just need 2 flaps, as Chicalet said, when you get the first crash buff, sniff the 2nd flap. The first no-no rush lasts 10 minutes and with the second, you get the 11 minutes.
