biting_ear_for_good_luck
A sort of trend that started in 2024, where allowing your girlfriend/boyfriend/whatever to bite_your_ear may bring good luck. It also apparently applies to artists drawing the act.
May depict the act of biting ear or imminent_biting.
It may have started with this tweet of Kan Kanna and Tsukine Kona (asset #24838068). post #7159043 may be the first instance of this phenomenon drawn.
