Get the welcher mug.
A Hip Hop beat or a Hip Hop song with a beat or percussion arrangement that is exceptionally dope. Meaning stems from slang applied to bass players who are said to "slap the bass." In this case, the term applies to the entire song and not just the bass line.
Yo this beat is a slapper for real! I can't wait to listen to it in my car. My subwoofers are going to be thumping.
