A reaction about a real threat where we have to protect ourselves, something that we are consciously aware of. It comes from the human brain and is brought about by genetics. This kind of fear keeps us alert and can be somewhat of a challenge. However, an irrational fear is something we fear, even though there is no direct link or threat to us.

A term used to reference cannabis/marijuana/weed.

1. Something big, hairy, and scary. (No, dude, not your penis...I said big :-) ) that can ACTUALLY happen to you, as opposed to an irrational fear.
2. Something not physically scary, but mentally terrifying yet very real...like an "aw, shit" moment.
