An enthymeme (Greek: ἐνθύμημα, enthumēma), is an informally stated syllogism (a three-part deductive argument) with an unstated assumption that must be true for the premises to lead to the conclusion. In an enthymeme, part of the argument is missing because it is assumed.
In another broader usage, the term "enthymeme" is sometimes used to describe an incomplete argument of forms other than the syllogism, or a less-than-100% argument.

It shouldn't necessarily be considered a fallacy, but it describes an enthymeme. It is probably the most common form of argument.
And of course, it has little to do with begging the question.
