Is there a name for when two keys next to each-other on a keyboard are played at the same time?

For example, suppose you play an F and an F#, or a B and a C, from the same octave at the same time. It usually doesn't sound very good. I've looked a while but I can't seem to find a name for it. Is there a name?

If you are looking for a word to discribe it and not a technical name I would go with dissonance or dissonant.

Generally you would call these intervals minor seconds. But depending on the "spelling" of the notes you could call the interval an augmented unison.
B and C is a minor second
F and F# is an augmented unison (the letters are the same so it is a unison to start, then the sharp on the second F augments it by making it 'bigger' by a half step.)
These intervals are considered dissonant and hash sounding.

so, if it sounds terrible normally, why does it sound decent when used from different octaves? eg: in a song called "eisoptrophobia," the bass note is F#0, and the melody note is G2. why do different octaves sound good vs. same octave?

It does not always sound horrible - it depends on context. There are fabulous examples of the use of the minor second in Bach and Mozart and many others.

@CrashRocks1419 Keep in mind that a minor second and a minor ninth aren't the same interval (although from a chord identify perspective they are the same pitch class.) For me, the minor ninth is much less dissonant than a minor second. Also consider the perception of dissonant intervals when the two notes are played by difference instruments. The dissonance seems softened when two difference instruments are involved. I image all this can be explained acoustically as simpler wave forms or interval ratios.
