They're NOT the same thing.
Official defenition:
Glitch: In Video Games, a glitch is a programming error which results in behavior not intended by the programmers. Glitches may include incorrectly displayed graphics, collision detection errors, game-freezing or crashes, sound issues, and others. Some glitches are potentially dangerous to the game save data.
Bug: A software bug is an error, flaw, mistake, failure, or fault in a computer program that prevents it from behaving as intended (e.g., producing an incorrect or unexpected result). Most bugs arise from mistakes and errors made by people in either a program's source code or its design, and a few are caused by compilers producing incorrect code
Allmost the same...
It is generally used like this:
In MMOs:
Glitch is a mistake in programming the game. Glitches are things, such as walking through walls.
Bug is something that a player can abuse to improve his in-game resources, or make a game easier and simpler to him.
In online(flash) games:
Glitch: Going "Out of bounds", going throught walls etc. and graphical errors.
Bug: Everything else.

That was maybe on purpose, a bug (glitch), or your phone can't handle the data being held from the place.

The glitch is broken.
The difference between Mandatory and Optional Triggers is that Optional ones say 'you can', Mandatory ones don't. Mandatory ones must be carried out if possible, even if you don't want to.Man-Eater Bug's effect is a Mandatory Trigger, it must activate, even if the only thing it can destroy is itself.
The Runescape No clip glitch was a glitch awhile back that allowed players to walk through walls, sadly this glitch was patched shortly after players exploited the glitch making the glitch as of April 6th 2010, impossible to preform. While this glitch was around many players used this glitch to reach unaccesible areas, such as Inside edgeville bank behind the bankers, but all they could do was "pretend" to be bankers. If players were to log out of Runescape Behind the bank while the glitch had been unpatched and then later logged back into the game after the glitch was patched they would simply log in outside of the bank booth they were "in". The no clip glitch was most likely one of the largest Runescape glitch/Bugs the game had and was very fun to use at the time.
