Debloating means to remove the bloat. Bloat means to puff up, or swell. Some people feel that carriers fill the phones with junk, such as T-mobile apps, that is, bloated. Some developers make ROM's without the junk or bloatware, thus debloated.
The simple act of google finds explanations of bloat, etc. That is a reminder to search. One of the things that separate noobs from non-noobs is the ability to use a search engine.
