MPDG is wish-fulfillment for the loser male protagonist. MPDG’s are one-dimensional and quirky in just such a way to make the messy, aimless, socially inept male lead somehow attractive to them. The male is possibly on the spectrum (more likely just an asshole), the MPDG is void of real personality.
A male protagonist dating a MPDG is like him dating his imaginary friend.
