peepocolypse
That time around Easter, where seemingly every store that sells anything worth buying is selling irresistible, brightly colored, delicious, marshmellow treats known as peeps. If not eaten quickly, and in the large amounts they are sold in, they quickly become stale... and present a choking hazard.
Dude, I just walked out of the grocery store and it's a freakin' Peepocolypse in there. 99 cents will buy you 40 stale peeps.
