Wiktionary mentions that «verga» can be a vulgar term for an erect penis. It mentions this along with several other definitions.
RAE mentions the vulgar term as the first definition, then lists half a dozen other definitions.
Google Images (I won't provide a link), of course, only thinks the vulgar definition has any relevance.
Should I take this as a clue never to use this word in polite company? Or are there contexts (aside from the technical context of naval navigation, etc) where it would be appropriate to use this word? If so, can you provide an example or two?
To clarify a little, Wiktionary says verga can mean "a long and thin stick, pole or rod". Is this a benign usage, or is this a vulgar usage, in which the long and thin stick is being compared to an erect penis?
