half mast 

When you're so tired that your eyes are only half-open and you can't get them open any wider.

Aww, you must be tired, you're at half mast!

When you are at full erection, you look like a flagpole after a tradegy.

So hard it hurts.

at half mast 

where you had a throbber, and then has died down, but is still not gone flacid, and is still erect, but has just lost most of the inflation, giving the impression of a pencil dick, but you've just not got a full-on boner.

i was having a wank the other day, and then i heard a noise, but then when i went back, i was at half mast

A partial erection.

half mastin 

The act of having sex without a full erection. Usually occurs when one is conciously grossed out by the person he is having sex with, but engaging her in sexual intercourse anyway just for the sake of busting a nut or due to sheer boredom. Almost always is sensationaless and unsatisfying, and prevalence almost always increases when drugs and alchohol are involved.

"Yo you fuck that bitch last night"?
"Yea, it was awful though, she was so doggish I was half mastin but I went through with it anyway cuz I'm a trooper."
