The adjective that describes someone whose schlong is longer than someone else. Can also be used to describe one with a very large schlong, one that is likely to be longer than many other schlongs.
NOT:
His dick was so much schlonger than my boyfriend's!
-the idea that we are talking about his schlong is within the word 'schlonger'. You do not need to say 'dick' As well, if you do not put 'sch' before 'longer' in that sentence, it would be functional.
