PNAS 

Proceedings of the National Academy of Sciences, a prestigious scientific journal with an extremely unfortunate acronym.

Scientist #1: Hey, could I take a look at your PNAS?
Scientist #2: Sure, as long as it's for science. <unzips pants and whips it out>
Scientist #1: GOD NO WHY I meant your Proceedings of the National Academy of Sciences!
Scientist #2: Oh, ok, sorry. Huh, that's the tenth time that's happened this week.

Take a guess. Look at all the other entries beginning with "p" and sounding vaguely like "p-nas" and just guess what this one means.

I didn't think there could be one more juvenile synonym for penis on UrbanDictionary until I saw the entry for "p-nas."
