What is “Penis enarglement”?
Have I missed something?
Email spammers learned that their message had been kill filtered using keywords like “enlargement”, so they intentionally misspelled those words to evade the filters.
However, for some reason, the “enarglement” misspelling was particularly popular, so Internet wits suggested that ‘penis enarglement’ was something grotesque and painful, perhaps a severe injury from a defective penis pump or something.
