Watching human vapor on Netflix season 1 episode 3. There is a scene where a wierd yakuza guy with thin eyebrows asks his dad if they could have a parfinee. Cursory google search didn't yield a result that made sense. Can anyone help explain what it is and why they father and son haven't done it in 3 years? Is it something that is lost in translation? I am watching the dub.
