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!

mb = Maybe.

A shortening that has occurred due to lazy internet gamers not being arsed to type in 3 more letters.

Often used in conjuntion with 1337, leet, omg, wtf and other internet gamer words.
