An unemployed man with too much facial hair and body hair. Usually too loud and extremely bad at expressing himself. A jailam may try to tell you he is outside your door but end up saying he is on the outside of a door like structure in your immediate vicinity. All in all a jailam is a useless cunt loved by his friends and hated by everyone who's opinions don't matter. If you find yourself a jailam keep him close and you won't regret it.
