A very messy and overall gross human. They try their best to exist, but just cant do it quite right. Mongrats often have a disgusting quality such as: hair, lankiness, clothing, stench, uncleanliness, etc. Some even exhibit multiple traits! Mongrats are often seen complaining or in a bad mood; watch out because they have a very small temper. They also cry when getting passionate, including when angered. Not to fear though! Mongrats are typically very weak, both muscularly and mentally. Mongrats also tend to avoid conflict, are generally very scared of their surroundings and tend to keep to themselves. The majority of Mongrats are also hopeless romantics, and usually show attraction to multiple genders.
Oh my god... Do you see how Blake is dressed today? And- OH GOD! The stench! Does he shower? He is such a filthy mongrat.
