break-out day

first warm sunny day on a college campus during the spring semester (typically March) where most females first break out their tank tops and the like to flaunt their pale cleavage. First day where all the white chicks lay out on random spots on the grass trying start their base tan, but get burnt.

Dude, I bet all these chickens get sunburned on break-out day this afternoon. I love break-out day... check out all these fun bags!
