We submitted a formal proposal for a dirt emoji to The Unicode Foundation in the Spring of 2024 and are currently awaiting their decision. So maybe what's coming next is Dirty Time in your phone, getting it and all of your future text messages all kinds of dirty. While you wait for this amazingness to happen to you, you can read the proposal (and see all the variants of the adorable proposed emoji)here.
Dirty Time welcomes inquiries and invitations.
