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!
