A meme originated a scene from JoJo no Kimyou na Bouken part 5 Vento Aureo.
The scene involves a tea party hosted by the Passione members to welcome Giorno Giovanna. After a brief conversation, Leone Abbacchio who is despising Giorno's idealism at that time, secretly peeing inside a teapot under the table and hands it over to Giorno to "prove [his] trustworthiness". Giorno then dramatically drank the whole cup of "tea" without hesitation, much to Abbacchio's shock. In reality, Giorno uses the power of Gold Experience to create a plant inside his mouth to absorb the "tea" without actually tasting it.
This particular scene later spawned the slang "Aba-tea" (アバ茶 "aba-cha"), which later became a byword for pee drinking/serving fetish.
