When it starts to get warm or nice outside after a long crazy season. Everyone starts to wear tank-tops, shorts and t-shirts. This is used after the winter time is over.

Get the Act up weather mug.
a song/rap made by city girls (written by: lil yachty). When a white hoe raps it they mess up all the words and when a black girl raps it they scream it at the top of they lungs and say every curse word clearly and correctly so the whole block can hear it. Appears to be played a lot at 'lit' nigga parties where cops end up shutting it down bc the black bitches get too loud.
