On a video about an explosion, I heard an announcer use a term that sounded like "blevvies." I got curious and Googled it; turns out it's an acronym. According to Wikipedia:

BLEVE, pronounced [...] "blevvy"[...], is an acronym for "boiling liquid expanding vapour explosion". This is a type of explosion that can occur when a vessel containing a pressurized liquid is ruptured.
