Usually someone named Kuro who thinks they know everything but often the opposite is true. This behavior often results in an obnoxious level of arrogance. The interaction usually leaves a bad taste in your mouth afterwards.
"Kuro is acting like they're right again. I looked it up. They're wrong. Again."
"Don't bring it up. Kuro will just shit-talk you."
"I know. Kuro is such a Salty Cracker."
When a you masturbate until your glans is bleeding then have your lover take a diarrhea dump. You now dip your wounded soldier into the preferably watery pile of shit then roll it around in salt.
