One who consistently participates in thievery of said "schlong". By thievery, I of course mean gobbling schlong in a variety of orificies; ear, mouth, you name it.
That guyDave is such a schlongburgler, he makes Clay Aiken look like the brawny man.
An abnormally large penis. Similar to a shlong, but even larger, hence the "er". Typically used in hyperbole, as shlong is generally sufficient to describe any penis, no matter the size.
Man, that dude Stephanie banged had a shlonger! That shit was like a third leg!
