The word can mean someone vomiting, a magazine, a magnum hand gun, and a large sized Trojan condom.
I was going to read a mag, but it was so gross I began to mag, then got turned on for some reason so put on a mag, and worked it so good that it shot out like a mag spitting bullets.

A man who nags.

In particular, any boyfriend who nags his girlfriend or any husband who nags his wife.
I need to dump my new boyfriend. He is such a mag! I'm tired of hearing that I don't respond to his texts fast enough.
I am so tired of my husband's incessant magging. He is the King of Mags! He can wash his own clothes and cook his own dinner.

The guy I slept with last weekend is such a maghole. He keeps texting me and won't get lost.

In England especially, a mag is an exceptionally short penis. The word derives from the word maggot which is the name of a wormlike insect larvae - the connection being that maggots are rather small. The word is used as an insult towards someone who is known or suspected to have a small penis. If the former is the case, then the one with the mag can duly call the insulter a pervert. Usually the accusation is false, and is believed by those who are insecure about the length of their own penis and who feel better about themselves by mocking others.
Haha look at that short kid. Because he's short he must have a mag. Let's tell him our conclusion: MAG!
