The term, "Issac" means someone who is really bad at marching band, and gets carried by the people on the cymbals. Usually, he is not the sharpest tool in the shed, but he is at times a nice guy, and that's why you keep him around. He is usually on the wider side, and he likes wearing cowboy hats.
John: "Dude, Michael is such an Issac!!!!"
Michael: "I do not suck at marching band!!!"
John: "Just keep telling yourself that bud..."

Get the Issacmug. To obtain a super high frequency note (as per the wicked game) one requires the assistance of a third party to enthusiastically cup and squeeze the scrotum while simultaneously inserting two digits firmly and repeatedly into the anus.
After a lengthy head cold the lead singer relied on a well delivered issac from the drummer in order to hit the high notes in ‘living on a prayer’!
