MCHAT 

MCHAT is when you talk complete and utter bullshit for hours on end whilst high on MCAT aka Mephedrone. This is due to the effect of MCAT which makes people extremely talkative.

"That Mephedrone was lethal last night, I was talking MCHAT alllll night!"

Mechatronics 

A mistake.
A program that lures innocent high school kids who want to make cool robots. Half the class end up becoming web developers.

"So... you transferred from ECE to Mechatronics?"
"It was a mistake."

Mahathi

Mahathi is a beautiful name for a girl just as beatiful. She is generally couragous and as (fierce as a lion). She is never (average) height. She may be short or tall, but (NEVER) average. Mahathi has a heart so big that it just doesn't fit inside her body, so she shall share her interests and passions with the world!!! GO MAHATHI!! Oh, and Mahathi will one day be destined to change the world like (never) before, for she is a girl who not only dreams big, but shall one day (DO) big.

Example:

Random kid: I aspire to become just like Mahathi someday!
Other kid: I know, RIGHT?!?! SHE IS MY ROLE MODEL, AND IDOL!! I love her SOOO SO SO MUCH AHHH!!!

Mahathir Mohamad 

If you're a Malaysian, you must know that he was the best Prime Minister in Malaysian history ever. Without him, Malaysia wouldn't be as rich as now. He led various economic and infrastructural developments. He is well-respected by Malaysians, regardless of races and religions.

We surely miss Tun Dr Mahathir Mohamad, the best Malaysian Prime Minister ever!
