Thumper is the user ID of someone on this forum, who does physical modifications to a projector (currently DLP only I believe) to greatly improve its performance. In particular, your black level is greatly improved, and so you end up with much better contrast and colors when watching movies.
The term "Thumperize" is used to describe the process performed by AVS member "Thumper" to enhance projector's performance. This process goes beyond a basic calibration, it involves modifications to the DMD engine resulting in, amongst others, drastically improved contrast levels.
