Emily's Army is a punk band consisting of four boys (Cole, Max, Joey, and Travis). They live in Oaland, California and play various clubs (including 924 Gilman Street).
Joey, the drummer for the band, is Billie Joe Armstrong (of Green Day)'s son. But the band should not be compared to Green Day in any way, shape, or form, for they are different.
In my opinion, Emily's Army is a kick-ass band and could bring punk back to the mainstream/today's world.
Going to Emily's house is a term that originated in Southwest Michigan in 2015. It is a code name for smoking weed as a term to tell one's parents to get out of the house.
