A Retard Unit is a form of expressing measurements the wrong way. Usually Europeans talk about the imperial system as a retard unit, but Asian units shouldn't be used either. Probably originating from 9gag or Reddit as retard units have, and is, looked down at, because who knows how many centimetre an inch is, and you sure don't want to waste brainpower converting. Comments reaching the top by simply converting foot, yards and pound to units the rest of the world understands. This started as a joke, now it's an actual importance in society.

As of now, the Americans should've learned their lesson, and stopped using inconsistent units, thus converting them before posting. If you spot a retard unit or simply an american, don't be shy to leave a little comment explaining what they've been doing wrong their entire life and leave a reminder for their next time, by destroy their self-confidence, insuring that they get off the internet, forever. OUT, JUST GET OUT!

BTW don't forget to leave a "Thank You" GIF to all the converters out there, you are the real MVP.
