Suck it 

'Suck it' was a fad during the 90's used by many children in elementary and middle school. This often went along with a motion; crossing one's arms at the wrists, and hitting the crotch area while they lean back. Though it may be coming back, if one were to ask a group full of children what the motion meant, it is probable that only one may know the answer.
When it became beknownst to the teachers back in the 90's, anyone seen in the act of such a motion would be prosecuted and/or severly punished (e.g. detention, whippings, time in the corner).

mah 

A bastardization of the word 'my' caused by children of this generation. Mah is used especially in conversations using AOL Instant Messenger (also known as AIM). Hooked on Phonics may have played a great role in this case.

In any case, this is used by children who think that they are cool by using these kinds of bastardizations in normal instant messaging conversations.
