When someone is being a Jew and you are have an issue with this person. Not to get you confused with a Jewish issue, like Adolf Hitler and Anne Frank. But, it would be appropriate in the context of someone being a filthy dirty Jew bastard and you have a medium to large sized issue with this person.
"What's the Jish man?" "I have a Jish to pick with you."
When you're anxiously awaiting a text from someone you're very attracted to and interested in but instead you receive a text from one of your friends about an unrelated and unimportant subject.

Most frequently used in the past tense as "jished"
-"So I waiting for this hot girl I met last week to text me back and Jake totally jished me to tell me about a dump he took."
-"I didn't respond to your text because you jished me and it pissed me off."
