The term 'spew out' can be defined as the act of expelling or ejecting something from a source. This can be done in a variety of ways, such as egesting, disgorging, and emitting. Egesting is the process of eliminating waste from the body, while disgorging is the act of forcefully ejecting something from the mouth. Emitting is the process of sending out energy or particles from a source. All three of these processes can be used to describe the term 'spew out'.
