Shamus: Well I've been at Half Mast for about an hour now, so it should be here anytime now

Cordon: Have you been stuffing your pants?
Bleu: Na I've just been sailing at half mast for about a few minutes now

Dave (to himself): Wow who knew that flying half mast in public would be so easy to get away with.
Lady (casually looking at dave): Wow that guy is at half mast, someone should really tell him to chill out

raising the mast 

Having an erection while in the pool; generally when swimming backstroke or floating on your back. This gives the image of a ship's mast going up.

You can also say that somebody "has their mast raised".

Bob- "Hey, see that guy raising the mast out in the pool?!"
Joe- "Oh, damn!"

Will- "Hey dude, go raise your mast. There are a bunch of chicks here who would love to see that."
Chuck- " No way man. You'll probably start taking pictures!"
