Yeah, it's an in-group exclusivity signifier.
Shame, math is some of the worst at this, everything is named after some guy, so there's 0 semantic associativity, you either know exactly which Gaussian term they mean, or you are completely clueless even though they just mean noise with a normal distribution.
edit: Currently in a very inter-disciplinary field where the different mathematicians have their own language which has to be translated back into first software, then hardware. It's so confusing at first till you spend 30 minutes on wikipedia to realize they're just using an esoteric term to describe something you've used forever.
