The bulk update request #9505 has been rejected.
The original intent of the sweatdrop tag is for when the sweatdrop symbol is used to signify a character feeling nervous or embarrassed; examples include post #5211005, the page image of Sweat Drop on TV Tropes, etc. Despite this, the tag seems to be heavily misused by a lot of people for regular sweat, even though that is not the original intention of the tag. Yet another tag made into a mockery and a joke by mistaggers, probably even worse than off-shoulder jacket.
Edit: changed to emoji, as per below.
