When a man inserts is fist into his ass and begins to urinate while having either Chlamydia or Gonorrhea.
Man - " I just found out I had chlamydia yesterday, so I went for a Bitter Lemon Tea."
A rude elderly person, who often despises anything new, or wasn't around when they were younger.
Man, I can't stand living with Maria. The Bitter Lemon is always getting on my nerves.
