MBS (Myles Bowel Syndrome) is a condition effecting the human digestive system, also known as, "I would rather have a shit than do any work today"syndrome. Common symptoms include the conscience requirement to take a shit at an hourly rate, and a near forced shitting commitment at the sight of a bathroom or portable toilet. It should be noted that a person suffering from the condition rarely has to take a shit on a scheduled lunch or bathroom break.
Todd: Dude that one hour lunch break was dope! To bad we got to get back to work...actually I'll let you get started where we left off. I've got a touch of the MBS today.

MB stands for megabyte, or 1 000 000 bytes.

Not to be confused with:

- Mb: Megabit (8 megabits = 1 megabyte)

- mB: Millibyte (theoretical)
- mb: Millibit (theoretical)

- MiB: Mebibyte (1 048 576 bytes)
- Mib: Mebibit (1 048 576 bits)

Capitalization matters!
