Help me win 250 quid

[Steedie]

Hey guys

Really really bizarre

My dads just phoned me and said that we can win £250 if he can get another word for consitpation beginning with M and ending with M and has 9 letters (we think?)

God knows what the competition is or the bet, I just want half of that 250 lol

So please help

Searching google like crazy

EDIT - Close...and delete

My dad just phoned again, said it was the a different medical term all together and he's off break now so never mind

Well that was a wierd thing for the afternoon
