this word is the word used to define the situation when many people are in a lift and one person lets out a bad smell. In particular an engo refers to the fact that it is impossible to define who created the bad smell yet everyone feels embarassed and some people want to throw up for inhaling such a bad smell in such a compact area.
"oh dear there is an engo in here. URGHHHH get me out"
