When one is unsure whether or not they are defecating or being fartaceous. Poot-sharting can be a somewhat scary experience for those poot-sharting. Poot-sharting is also very rarely used with correct verb conjugation and is often purposefully used in defiance of English grammar.
First discovered in the song "I'm In Miami Bitch" on the 2009 album by LMAFO, Party Rock, 'poot smack' is known as the sound created by the beat of music, typically a bass drum kick ('poot') and a cymbal hit ('smack'). 'Poot' and 'Smack' can be arranged in any order to deliver many different background beats for songs.
