lofasz is horse penis in hungarian not dick, if it would be dick it would be spelled like ~ló tök~ but it's ~lófasz~ . Usually it's used as an insult, hungarians tend to use it a lot :))
The harshness of it depends on the context and to whom / what you address it.
-Ez mi a lofasz?
-NEm tudom, sosem lattam ilyent meg! :))
