Top definition
A bag with one strap worn by metrosexual or homosexual males. Looking suspiciously like a manbag, but usually with a utilitarian design lacking the flair or self confidence of a genuine man bag. Consequently it is hard to determine if wearers of such an item are either metrosexual or homosexual and are more likely to be bicurious.
Brian: Geez Dave, whats with the man bag?

Dave: Its not a man bag, its a Dutch Marines Knapsack.
