Tractor Cannon is an exotic shotgun introduced in Destiny 2 in 2017, known for its Void blast that repels enemies and suppresses their abilities. Its nickname as a boop cannon helped it become a favorite for playful PvE moments and montage edits. The short firing sound spread through gaming clips and soundboards because it is instantly linked to that knockback effect, similar to how players reuse a pump shotgun sound for impact. It remains popular for memes about pushing bosses, teammates or objects aside.
