This term in no way insults the individuals who genuinely suffer from these conditions but is however generally directed at those who have no excuse for their lack in co-ordination & mental abilities.
Likely candidates for wearing this name can be discovered by observing ones friends/mates & watching/waiting until an opportunity presents itself.
These opportunities may be found on the sporting field, in the academic arena, walking down the street, or even when simply eating a meal.
A "downtarding" event is not easily missed as it is usually followed by fits of laughter directed at the offender or the feeling of wanting to injure the prospective "downtard".
If you are wishing to brand one of your friends/mates & are unable to find any solid basis for the naming of a "downtard", A temporary branding can be authorised even tho sufficient evidence cannot be supplied. This will give u a sense of achievement during your hunting, & will likely cause ur friend to contemplate lifes most haunting question... "am I a downtard?"
Follow your instincts...
