Aliasing passion → passionate
Link to alias

Reason:

Obvious.

EDIT: The tag alias passion -> passionate (forum #252654) has been approved by @Rainbow_Dash.

..those both tags are extremely subjective and vague so idk if either of them should exist in first place

Eh, both seem like bad tags.
Ambiguous, subjective, and without definition, should probably be handled the same way horny was. There are much better tags that could be used, such as romantic_couple.
