Bid-whacking..is when you see trades being executed at prices found on the BID column of Level 2...Bid whacking will see prices fall.

When someone just sells at the bid rather than selling at the ask. Sometimes it's an attempt to drive the price down by continually "whacking" the bid

It's when someone sells their shares on the bid instead of the ask.
