bisweptual 

In rowing (Sweeps, not sculls), it is the ability to row on both the port and starboard side.
Because scullers row with two oars all the time, they generally tend to have better technique, and are more inclined to be bisweptual should they ever switch over to sweeps.
It's cleverly worded to sound like "bisexual", so those uninitiated to rowing will think you're mysterious and rebellious.
As far as being a hackneyed expression, it's the equivalent of saying that you're bi-sacksual.

Coach: Tom, Pete is sick, and can't row today. I know you're a starboard, but he's port, and we need someone to make the change.
Tom: Sure coach, I'll do it, after all, I'm bisweptual.
Coach: Ah, I see, so you could say that you row both ways?
Tom:...that's right Coach, anything for you.
Coach: Alright, well today you're going to be stroking it also. I expect we're up against some stiff competition.
Tom: Well I'm sure we can beat them off, if not, I'll just jack up the stroke rate.
Coach: You're sure you can handle that?
Tom: Hell, they'll be so scared of me, they won't even come.
Coach: Ok, this is getting too gay.

Biceptual 

A person, usually male, who defines himself by the size of his biceps. Biceptuals, often found on Long Island, are frequently seen out and about in the summer months, and they are known to wear extra small t-shirts. They compensate for a lack of intelligence with the size of their biceps.

Nah, let's go to a different bar. That one is packed with biceptuals.

Bisleeptual 

If you can fall asleep on your left or right side. You are more bisleeptual if you enjoy falling asleep on both sides considering most people flip and turn to different sides throughout the night anyways.

Alexa - "Do you like sleeping on your left or right side?"
Zac - " I am bisleeptual, I enjoy sleeping on both sides."
