amrdrn rbaf sod gt

WTF you might be asking. Well, I'm on AOL talking to my mom via IM and this is how the conversation goes. things in ( ) i added for explaination

Me: Well it's time for me to take my pills and get ready to go ninites (what my 18 month old says when he's tired)

Mom: amrdrn rbaf sod gt

Mom: what was all that jumble I typed?

Me: lol I don't know I didn't type it

Mom: Neither did I

Me: well then who did? bridget? Keesha? (her 2 dogs)

Mom: the candy cane? (her animated buddy icon on AOL)

Me: if the candy cane is typing i'm done using computers

(We then get into a discussion of what it could have been she was trying to say)

Me: maybe it was "i am getting ready for bed so good night"

Mom: no i don't think so

Me: well then it must be "am ordering roast beef sod get"

Mom: either way you look at it something is wrong

Me: lmao

Mom: what does lmao mean

Me: laughing my ass off

Mom: pmplso

Me: what? are you not typing again?

Mom: no i'm laughing so hard i'm crying and i can barely see to type

Mom: peeing my pants laughing so hard so it should be pmplsh

Me: rotflmao and that means rolling on the floor laughing my ass off

Mom: well i am going to bed so good night

Me: so maybe I was right that "amrdrn rbaf sod gt" means "i am getting ready for bed so good night"

Mom: maybe

Me: well then "amrdrn rbaf sod gt"

Mom: whatever you say RAINBOW (from mad tv)

Me: Night

Mom: night

By the end of this conversation I can't see from crying so hard from laughing.

So my question is... WTF does "amrdrn rbaf sod gt" mean?
