Most MOOP I pick up are glowsticks. I would rather toss them in my moop bag after hearing about the glowstick that got lost in a girls vag at BMan 99 or something like that.
Best MOOP Ive picked up over the years have been BMan Buttons and green bud.
This year I found a really cool button in Exodus line (still a good time to moop)
I looked at the big button and it was what appeared to be an artistic representation of the Man on fire. It was flames, orange like it was burning. cool!
I wore it all the way home and realized when I got home it was a pic of the center of a tomato. OMG RAD!
