Based on this thread over at Reddit, I'm curious to see if anyone has any weird nicknames for stuff in-game as well. Let me past the OP's first para.

As inspired by this thread, I decided, with some encouragement, to see if I can get at least a small organized list of the weird things we call bosses, items, supers, etc., in Destiny. What got me thinking about this was that, in my clan, we call the void seekers that Shriekers emit when you kill them "Liam Neesons," because they will find you, and they will kill you.
We use some of the other commonplace ones like "Palpatine" or "tickle fingers" for a stormcaller, Rockets McDickface, etc.
Let's try to get some weird vocabulary shared from all corners of the tower!

I guess I'll go first:
Stormcallers - Ticklefingers
