Kibum is probably one of the sassiest idols out there.
Suga is also extremely sassy, always judging you...
Sehun is one sassy maknae
Bambam isn't as sassy as the others, but he's definitely in my top five
And lastly, Jaehyung. He's climbing up the list of sassy idols really quickly (I mean who's cocky enough to to post a photo like this on their own twitter lol).
