A trans woman (male to female for those uninitiated) who is attempting to present as their assigned gender at birth to avoid difficulties when people might notice they have transitioned.
For example, a boymoder might cut her hair short and wear baggy clothing in preparation for a family gathering so her family doesn't know she transitioned.
"I hate being a boymoder. Working from home is nice, but whenever I have to come in for a meeting I'm looking out of place with my casualbaggy clothing."
When you cannot fall asleep because someone is sleeping over, hogging the covers or thrashing wildly. You may even really love this person creating the insomnia but the fact still remains: you need your sleep, especially before a big test! Ways to avoid: tell them to buy a bigger bed, push them off of the bed, or make an excuse as to why they or you should not sleep over.
Paris Hilton: OMG Nicole I didn't sleep at all last night!
Nicole Richie: Were you: out, making another sex tape, having a fake career, partying, or being your usual slutty self?
Paris: No, this was after that I had Boysomnia and couldn't get a wink of sleep.
Nicole: Oh!
Boymoders are transwomen who attempt to present as male while transitioning with feminizing hormones. Due to social anxiety, they're often afraid of showing any outward signs of femininity while being completely unaware that everyone can notice the changes. You can generally find them wearing oversized hoodies and women's skinny jeans regardless of the weather.
"The boymoder tried to cover her breasts with a baggy hoodie, oblivious to how visible they were through it."
