IDST

slang An initialism of "if destroyed still true," written alongside instances of graffiti to indicate the sincerity and immutability of what it says. Primarily heard in UK. Someone had carved "Matt & Jenny 4EVER IDST" in the side of the tree. As part of the protest, the youths denounced the prime minister in graffiti marked "IDST." It's easy to write your initials alongside some girl's and "IDST." It's a lot harder to love that girl for a lifetime.
