1. A name given to mainly females. This name can be a short form for Megan, Margeret, Maggie or Megumi (Japanese). Meg is usually an English name, with Greek origin meaning "pearl". (μαργαριτάρι, margaritári)

2. A million bytes of data, short for megabyte, or 1/1000th of a gigabyte. This is derived from the SI prefix -mega which has a multiplier of 1,000,000. A typical 1920x1080 JPEG image or a minute of mp3 audio at 128kbps will be about 1 meg in size. A floppy disk holds 1.44 MB, while a 64GB phone stores 64 thousand megs.

3. A massive shark known as the Otodus megalodon that went extinct 3.6 million years ago. It can grow to a length exceeding 20m (65ft), weighing over 60 tons (130,000 lb), and has a bite force of more than 100 kN, or 25,000 lb-force.
Meg is considered very attractive. If you have met Meg, she would be usually swarmed with many guys around her.
Hi, my name is Megumi. You can call me Meg for short.

I have been trying to download this 700 meg movie file. Problem is, it takes forever on my dial up connection. I should upgrade to a 100 mbps broadband line.
My phone is running out of storage space, it is down to barely a hundred megs the last time I checked. I guess I can't download this video file then.

Have you watched The Meg? It is a movie about a giant prehistoric shark attacking an underwater facility. Its jaws are wide enough to consume a whale whole!

The first time you meet Meg, her beauty will strike you, but she is very quiet... that is, until you get to know her-- then she won't shut up! And that's a good thing! You will never get sick of Meg and her goofy antics. She can keep you up at night laughing or talking about the deep stuff until morning rolls around... there's no in between. Meg is loyal to her family, and always makes time for them. She is true to her friends, and wouldn't imagine stabbing them in the back. Meg is kind to everyone, and everyone is drawn to her magnetic personality. Meg is beautiful-- inside and out!
Easton: Who's that girl over there? She's beautiful but seems quiet.

Lily: Go for it! Meg's shy at first, but once you get to know her? Dang! She makes me pee my pants!
