TEA/TEB (Triethylaluminium /Triethylborane) aren't hypergolic - they're stored mixed in a single container. They're pyrophoric, which means they burn on contact with oxygen or any other oxidiser. TEA is so reactive it will ignite on contact with liquid oxygen - very few things can do that. The SR-71 used TEB to ignite its engines, as JP-8 was so hard to ignite.

Thanks for the additional/corrected information, I'll try to remember that distinction!
