Not necessarily. Although penis-based meanings (in the sense of to fuck or to have a big penis) are more frequent.
What I think is responsible for those rare occurrences is the confusion between shlong and shlogn (from German schlagen - to beat):

Shlogn - שלאגן \SHLOG-en\ Verb:
To beat, hit, strike; mint (money); fight [with zikh].
