People who complain about trivial problems but don't bother to make the positive change themselves. Some characteristics of hardars are complaining about the past, being overly emotional like the movie bedazzled starring brendan fraser, being insecure, can't keep a coherent conversation and ignoring the truth given to them. Simply put, you can also consider a hardar who is lost in the sauce.
"Bro wtf this man being a hardar right now."
"Jeezus, he/she hardar'ing up the ass."
"Fookin hardars."
"Person 1: I can't believe she left me man, I really loved her.
Person 2: Bro yo ass was drunk and treated her like shit; of course she gonna leave you. If you would have cleaned up your act she probably would have stayed with you.
Person 1: *gulps beer*
Person 2: *sighs* freaking hardar."
