Amongable (invented Spanish): two people mutually renounce what they actually want out of being too kind or too friendly, thereby jointly achieving the daftest outcome. Canonical example: both feel like cheap Chinese food, each assumes it’s too shabby for the other, they end up somewhere expensive and bland. From amable (kind) + hacer el mongo (to act the fool).
