GISM 

GISM is an acronym for Geographic Information System Map.

A geographic information system (GIS) is a computer system for capturing, storing, checking, and displaying data related to positions on Earth's surface. By relating seemingly unrelated data, GIS can help individuals and organizations better understand spatial patterns and relationships. Most of the information we have about our world contains a location reference: Where are USGS stream gauges located? Where was a rock sample collected?

When the GIS data is incorporated into a map it is referred to as a GIS map or a GISM.

Gism Face 

A person who loves to get a fat load or a wad or straight up cum (gism) all over their dome.

They usually grab the cock and smack their face with it while it's expelling the gizz. If the gism face is a guy, he will just rub his face inside the pussy like no tomorrow.
You can usually spot a gism face because they usually have a little gizz on their face.

Reference the movie 'Bruno" where meets the ghost of Milli Vanilli, if that scene was real, Bruno would obviously be the gism face.

Dude, that chick must love the cock, she's got a major gism face.

Hey, you've got some sour cream on your cheek, wipe it off before someone mistakes you for a mega gism face.

Oh man, I gave the best face last night, ended up with a MAJOR gism face.

(theme to Superman begins)...it's GISM FACE!
