When a man believes he is running a tight ship but in reality his girlfriend is the one who calls the shots in the relationship.

Depending on the level of control the girlfriend exerts, the man maybe designated as one of the following;

1. Sailor Pants
2. Captain Pants
3. Admiral Pants

And the ultimate....
4. Lord Nelson Pants

'Hey Captain Pants, would you like a Baby Sham?'

Alternatively when referring to the individual, his 'Pants Rank' is sufficient;

'Sailor, what time is your Mrs arriving?'

'I hear Alicia moved in and promoted Matt to Admiral... suppose that's the last we will see of him'

AKA Captain Malcolm "Mal" Reynolds of the vessel Serenity. Known for being particularly dour, with a harsh sense of humour. Although he finds it difficult to open up, it's obvious that he's a good guy beneath it all. Portrayed by Nathan Fillion on the now-cancelled sci-fi show Firefly which lasted just one season on FOX from 2002 to 2003. The nickname was first coined by the character Kaylee in the episode "Shindig".

An affectionate word used by Firefly fans to refer to the character of Mal, and (more rarely) the actor Fillion with reference to the show.
Example 1 -

Mal: Just be careful. We cheated Badger out of good money to buy that frippery, and you're supposed to make me look respectable.

Kaylee: Yes, sir, Captain Tight Pants

Example 2 -

Fan: There was a rumour that Captain Tight Pants himself would turn up at that convention last week!
