To reveal they're all playing off-meta picks, and some are in clubs together... http://www.reactiongifs.com/wp-content/uploads/2013/06/nope.gif
maybe thats just me though, lots of people who play off-meta are skilled at the off-meta champ
As a Kog'Maw main I find it flattering and saddening as it is a sign that Kog'Maw is outclassed by many adcs in terms of playability
As a katarina bot main, I can say, you better make like that Octopus when you see me, unless you're grouped with your jg and he ganks me a ton... then I'm the octopus, or also if your supp is leona, then I'm the octopus again.
As a Kindred ADC main I can approve.
It is less that they are generally good and more that you don't know their champion's capabilities in the current meta which makes it hard to play vs them.
