It is two words in juxtaposition. Perhaps you need to look them up seperately.
But essentially a "Guru" is a teacher, a master, or a recognized leader in a field. While "Penetration" is a type of sexual practice (ie: intercourse between two consenting adults).
Therefore a "Penetration Guru" is a sexual master - from the Shaolin Monks of the Kama Sutra.
Whisperer: (Yes, I've checked the diary) is it REALLY that difficult to work out?
True story: I swear this is true - it happened during the last week - and you should be able to pick it up in the press. I heard it on BBC Radio 2 Steve Wright's afternoon Radio show. (About last Wednesday/Thursday 15/16 Dec). Roughly;
Theives in Bangcok were in for a surprise when they attempted to rob a convention of monks at (some posh hotel). Being monks, the thieves thought that they would be an easy target, and that if "caught", that the monks being all sweetness and light would forgive them.
Actually it was a convention of some of China's highest ranking Shaolin monks - and the poor thieves had their sorry asses well and truely kicked by the time the thieves had phoned the police to give themselves up!
Somehow, I can not see the same thing happening at a Jehovah Witness convention!
In Mr. Moss' defence: I don't think Clayton's song is purely sexually connotated. Of course, there's a strong sexual component to the song (that's true with most rock songs), but in the song "penetration" also refers to pervasion and penetrance in general - psychological - terms.

Errr...What was wrong with 'penetration' Phil?...
Doesn't penetrance also simply mean "permeation/penetration/pervasion" in a medical context ? And I think (judging from its German equivalent "Penetranz") it can also mean "obtrusiveness".
I may be wrong.
I still think that Penetration Guru is not purely about sex though :-)
And no pun intended regarding the poster of the same name (great bloke that he is) !
