Like a schlong, but longer. Clearly superior over the better known terms 'schlong', 'schlort', and 'schledium', the Schlongest is the schlongest schlong around. Common people that have this size of pp are often named 'Vick', 'Alohi', 'Ozzy', or 'Bryson'.
"Hey look did you see Bryson that other day"
"Yeah man he had such a big schlongest it crushed the entire building'
Alternative spelling of longest, used often during Billy Joel karaoke.
Whoa, oh oh oh, for the schlongest time.
