In a video game, to progress through the game at a very slow pace, much slower than designed, in order to artificially lower its difficulty. E.g. engage fewer enemies at a time, kite them for extended time, use a lot of time to heal and stock up with consumables between encounters etc. Can be used as a derogatory term if it abuses game mechanics to the point of breaking immersion. Some games have measures to prevent this tactic such as set timers to complete each part or evolving opponents who would outpace and overwhelm you in such a case.

Viewer: "Read: turtling"

Leah: HAH TURTLED
Talon: what does that mean?
Leah: Turtling is when I flipped your hood and gave you a turtle shell!
