Inside has developed from being
a preposition simply meaning withing a building, to meaning just
in the world. It is an incredibly unhelpful way to assist anyone who is in genuine
need of assistance in locating something. It can also be a reference
to someone's testes.
Tesch: "Have you guys seen my pregnancy test?"
Shoey: "Yeah, it's inside."
D-Ran: "Inside, Brutha."
Tomoi: "Inside THESE
GUYS." (Points to testes)
