The tag alias #56312 coffee_mug -> mug_of_coffee has been rejected.
Reason: i think its most useful to classify mugs based on what they contain, and I think writing the tag this way conveys that better.
Any mug becomes a mug_of_coffee when it has coffee inside. Simple and unambiguous.
EDIT: The tag alias coffee_mug -> mug_of_coffee (forum #325895) has been rejected by @Rainbow_Dash.
