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!

A funny, intelligent, kind and skilled girl who deserves everything. She is extremely humble, sometimes not seeing her own worth, and many people know she is probably better than them at a lot of things, though she wouldn't say it. She would spend hours doing things like reading, cooking and baking which all her freinds find adorable, just like she is. She is a next level of beautiful that she makes all those models people thought were attractive look like a dumpster full of crap.

If you end up falling for one, which you will, you will spend your days watching your Meg-Senpai around the corner and groveling at her feet so you are ready to fufill her every want and need. Just hope she sees you as her freind.

Everyone needs a Meg. But she also has a little morbid and dark side which scares most people, but is so loveable. So enemies beware , because if you hurt her or her freinds she will go yandere on your ass.

(Symptoms of falling for a Meg include: Blushing, Nausea, Stuttering, Light headedness and Notice Me Senpai Syndrome)
Guy 1: Oh my gosh Meg is so purrfect!
Guy 2: Yeah I see what you mean by if that's her there by the table. Is it?
Guy 1: (Drools)

Meg: Hey guys! Wanna try these cookies I made?
Guy 2: Y-yeah okay
Guy 1: ...
Meg: (Gives cookies then pats Guy 1 on the head and leaves)
Guy 2: She really is a Meg

Megs are nice as hell, funny as hell, likeable as hell, cute as hell--basically, she's fucking hell. She's a heartbreaker without realizing it. Meg might be short for Megan or Megumi. She is the vision of a perfect girl. If you fall for a Meg and she falls for you, you have the title of the luckiest dude in the world. If she doesn't feel for you, you're in deep shit. Symptoms include: depression, insomnia, increased stuttering, increased staring at her, and increased praying to God.
Dear God,

Have mercy, I am dying. End these feelings for Meg quickly, I beg of you.
