Rocket Jumping 

A mechanic in Team Fortress 2 that allows the soldier class to maneuver great distances at a high speed by shooting rockets at surfaces (floors, walls, props, etc), while sacrificing some health and ammo in order to do so. It is also essential to the process of market gardening, and by extention, Trollgier.

Have you seen some of the top Soldier players do rocket jumping? They go so far so fast!
