lead zeppelin 

Lead Zeppelin refers to how Led Zeppelin achieved there name, when drummer Keith Moon from band, "The Who" said that they'd go down like a lead balloon (which at the time was a british expression meaning that theyd fail horribly) when asked to join the band. Led Zeppelin later took this term and used it as there name but changes the spelling to "Led" to avoid pronounciation errors.

"that'll go down like a lead balloon",
it wasnt actually Lead Zeppelin it was Lead Balloon,
and Led Zeppelin was the name of the band,

lead zeppelin 

A threat. The act: getting a hot girl/prostitute/total slut bag to go in and start rubbing/sucking/engaging in sexual congress with the subject of your threat. Then, shortly before ejaculation, but at full and inescapable arousal, you burst into the room and punch said target in the head of the dick aiming towards the base of said penis. The result: complete and utter destruction of said person via ruination into the base of their wang.

Jims: Dude, don't go there. I'll give you a lead zeppelin.

Slapdick: The metal band?

Jims: No the ruination of your dick bro.
