Girthgasm 

When a woman or gay man has an orgasm primarily due to the girth or the thickness of the penis they're being fucked with filling up their pussy or booty walls and making them feel so full, leading some women to squirt over and over again.

Nicole: Oh my God, it's so good, wow, I feel so full, right there, right there

Shane Diesel: Yeah cum for daddy slut, cum on this fat cock, have a girthgasm and go home and tell your husband, Myers, all about it

birthmasday present 

A present that unfortunate kids like me must get when you want something that the family can only afford if you combine your birthday present money with your Christmas present money. Thus, you don't get anything for one of those holidays.

"Dude, how did you get that iPod Touch?"

*sigh* "It was a birthmasday present."

birthmas 

The period from about December 20th - January 5th in which a person's birthday may fall and they get a "Christmas/Birthday Present". I.E. They get one present for their birthday and Christmas instead of two due to their birthday falling so close to the holiday.

I got screwed again on presents this year...my mom decided to get me a birthmas present to make her holiday shopping easier and cheaper.
