Jealous and envy can both be shown with the same sign that uses an "X"
handshape near the corner of the mouth. Imagine sticking a fish hook
into your lip and then twisting and pulling it a bit. (Um, sorry, not
the most pleasant of visualizations eh? But then again, envy is seldom
ENVY or JEALOUS:
"Is your boyfriend the jealous type?" = YOUR BOYFRIEND JEALOUS EASY?
There is an initialized version of the sign "JEALOUS" sign that is
specifically interpreted as "jealous." Even though this
initialized version is fairly widely used by lots of people, I recommend you
stick with the more general "X"-hand version (above).
I encourage you to study human behavior and you may notice that sometimes
when people experience the emotion of envy or jealousness they may stick the
tip of one of their fingers into their mouth and bit it a bit.
