Magnum

A scrawny kid with a huge wang. A Magnum usually plays pansy "sports" like ultimate frisbee and bowling. Don't expect to see a Magnum out around the town at night because they usually go to bed at 10pm. This is because they are so tired from having to lug that huge mangina around all day. Even though Magnum's have large love sticks they usually strike out with the ladies, coming off as cocky and annoying. The cockiness usually develops from their knowledge that they are more "man" than the average joe.

"Really Magnum, put that thing away!"

Magnum

A round with a greater amount of propellant than a standard cartrige or the wepon that fires this ammunition. Named after the largest size bottle that champagne is sold in (almost 1/2 gal.)

The condom you can't fit in.

'Yer only five inches... this won't work... you can leave, Brett.'

'My arm... it fits in the magnum... that's sick...'

Magnum

The standard way to describe a glass bottle which holds 50.8 fluid ounces of champagne. A regular bottle of champagne holds 25.4 ounces, therefore a magnum contains the same amount as 2 regular bottles.

I was going to get a bottle of champagne but decided to get a magnum of champagne instead because more people are coming than I expected.

Magnum

a nickname that really lame dickwads try to give themselves because they think it makes them sound cool, or they think it fools chicks into thinking that they have a big penis, when in all actuality, they probably have the tiniest choad you've ever seen.

Guy #1: Can you believe Billy wants us to call him Magnum?

Guy #2: What a little choad! That grundle troll is annoying as fuck.

Guy #1: Yeah, I know what you mean. I wonder if he asked his manager at T.G.I.Friday's if he could put "Magnum" on his name tag.
