green out 

A green out is a cannabis induced physiological or psychological panic attack. Symptoms include sweating, nausea, heart palpitations, hypervigilance, paranoia, and the fear or feeling that you might be dying or about to die. A green out is typically caused by smoking or ingesting too much cannabis too quickly.

Green outs are generally brief experiences and may be followed by exhaustion or drowsiness, or a rapid sobering.

Unlike black outs, memory loss doesn't tend to occur during a green out due to the intensity of a green out.

Memory loss is much more likely to occur during a long, sustained session of cannabis use.

Unlike alcohol, cannabis use affects short term memory (what was I saying?) and not long term memory (what did I do last night?).

Sativa strains may be more likely to cause green outs (while indicas are more likely to leave you stoned)

Person 1: Dude, don't smoke so much. you'll green out.
Person 2: pshh, green out, sure, whatever.
(green outs vary depending on the circumstances so it's difficult to describe a specific example, and it can take multiple green outs to really understand what's happening when you have one).
Person 2, now an experienced pothead: Dude, don't smoke so much. you'll green out.
Person 3: pshh, green out, sure, whatever.
