Long schlong telegong is a common phrase among germanteachers when singing along loudly in the classroom. It can be written as Ľ0ňğ Șçhĺòńğ Țėľêğõňğ, too.
"Yeah Ľ0ňğ Șçhĺòńğ Țėľêğõňğ ❤️❤️❤️", sings my teacher. "Aiaiaiaiiai Long schlong telegong", answers my colleague.
Just like the name implies, a cock that's oblong. It is thick at the tip, from which the shaft tapers to the base, much like a Louisville Slugger.
"I watched a video of this hot bitch brushing her teeth, in the nude, which was great until the camera panned down to show the he/she's oblongschlong whirling around like a propeller. The horror! The horror!"
