A guy who's name starts with a J (examples: Josh, Jordan, Jacob etc.). By default, a J guy is an automatic red flag in the dating world. A J guy generally embodies particularly undesirable traits which may be undetectable at first. These traits include (and are not limited to) cheating, ignoring, narcissism, fear of commitment, pushy, and being a huge douche lord
in general. All women should be highly wary when dealing with any type of J guy (proceed with caution).

"It's to be expected. He is a J guy after all."
