a low energy beta emmitting isotope of hydrogen containing 2 neutrons and 1 proton.

i spilled tritium on myself but didn't worry about it because the radiated particles aren't energetic enough to penetrate the layer of dead skin that covers my body

Trivium Fan 

Trivium fans are the best fans, they love headbang, chill and have a great time. There also probably a guitar player that loves early thrash such as Metallica and Slayer. You'll never meet a fan that is as open to your music as a Trivium fan. One way to hype-up a Trivium fan is to turn anything on from Ascendency, that shit slaps!

Trivium fan: You like Killswitch, check out this shit!
Turns on Like Light To Flies, too the max.

Trivium 

One of the more modern metal bands of the 2000's that have roots in thrash with Metallica being their biggest influence. They are one of the most talented bands of the new age and continue to make awesome music

Trivium is not emo.

If you think Trivium is emo, you might as well be listening to St. Anger

tritium 

Irradiated gas utilized in military instruments and timepieces for the sole purpose of lighting dials or numbers during times of complete darkness.

This gas emits enough light for easy reading of a timepiece in compete darkness and will last for 25 or more years.

I have a Marathon T-SAR watch that uses tritium gas to light the numbers so that I can see them in the dark.

Trivium 

A band that punk ass metal fans don't like because one of their albums entered the Billboard top 40. They didn't copy Metallica. Metallica might've influenced their some of their work.

Fake Metal Fan:Fuck trivium!!! Sellouts! All they care about is money! That's why they're so popular!

Smart Person: Can't blame them for writing music that people actually want to listen to.
