Male Loneliness Syndrome, known as MLS, is a "mental disorder" described by heterosexual males, most commonly Incels, as something caused by female rejection. Realistically, most people who claim to have this disorder typically put in little-to-no effort to build relationships or trust in women, and simply want to blame women for how unfuckable they are, as well as the fact that they are unfathomably socially inept.
John: I overheard Cody talking about his Male Loneliness Syndrome to Amber, no wonder she keeps rejecting him!
Dave: Yeah man, he really needs to learn how to socialize... I almost feel bad about it.

The feeling when the ending for a programme of show reminds you of of how you felt when watching LOST for the first time, where at the end of every episode you would be all 'WTF just happened? Don't end there! Nooooooo'
I had a bad case of Lost Loneliness at the end of Catching Fire...
Did you see Captain America? I left the cinema full of Lost Loneliness!
