A sprachman is generally used in reference to a Jewish overgrown man-boy who is a lover of his mom and has a FUPA. A sprachman may be found in his mom's bed cuddling with her or in his backyard building hanging tomato gardens. If you encounter a sprachman he will probably be with a girlfriend who is quite far out of his league and he will be on his way to his mom's house for dinner. A sprachman can also be found playing with angry, drunk midgets (often called a Garganese).
