When a male puts his testicles up a females (or another males) anus, the receiving female (or male) then proceeds to squeeze out said testicles, as if having a poo.
Pleasureable for both parties involved.
Like Tea Bagging, but anal...
If someone calls you "Earl Grey" as a nickname, they are calling you a hot tea (hottie). Derived from the pick up line, "Your name must be Earl Grey, because you are a hot tea (hottie)!".
