Getting rekt originally described losing an over-leveraged crypto position to a liquidation, and it now covers any large, fast, self-inflicted loss. Rekt is the outcome; blown-up is the version where the account does not survive it.
The word is used casually, which flattens a real distinction. Losing a planned risk unit is not the same event as losing a position that was never sized to survive an ordinary move, and only the second one is usually meant.
