Oshikko Sensei

The term (おしっこ先生) is a Japanese slang phrase that literally translates to “urine teacher.” It is most commonly encountered in online communities that discuss or role‑play a particular niche fetish involving urination (often abbreviated as “oshikko” or “piss”). The “sensei” suffix adds a playful, authoritative twist, suggesting a character who “teaches” or guides others in the context of this fetish.
