Presumably, "general education [credits]."
In the US, major requirements are broader than elsewhere. For example, students of any major may be required to take a year of a language, or two or three arts classes (for the sciences) or two or three science classes (for the arts).
So, "general education" often refers to these, or entry-level courses like Chemistry 101 that students will often take at community colleges where they are cheaper, and sometimes easier (i.e. not weed-out classes). Often class sizes are smaller, too.
Suggested in the comments was "general electives," which would be similar.
You might need 200 credits to graduate, but your major only prescribes 150. So your last 50 credits would be "general electives." Popular ones at my alma mater were drawing classes, Earth Science 101 (space!), or stuff like "Human Sexuality" or "Taboo Language."
They are slightly different in that "general education" credits are required to be those classes, where as electives are class you take just to reach a number of credits.
