The tag alias #56548 pickle_rick_(character) -> pickle_rick has been rejected.
Reason: Same thing; I don't really see any reason to have two separate tags for this. The meme could technically be referenced without the Pickle Rick character appearing itself, but that doesn't really feel like a necessary reason to have an entirely separate tag just for the character.
EDIT: The tag alias pickle_rick_(character) -> pickle_rick (forum #327156) has been rejected by @faucet. / Rejected in favor of the BUR.
