Is a use all word, to be placed almost anywhere in a sentence, to meananything. It works much like 'x' in a math equation; x + 23 = 37. Nearly any word can be replaced with Jarm.
"I just took a huge jarm. I think it was something I ate."
"I just jarmed out at the Gym. I did ten jarms on the Jarm Press."
When writing and meaning to spell "harm" it is the action of missing the"H" and hitting the "J". Then giving up on grammar altogether and sending the message anyways.
