A forced getup, also known as a jab lock or simply a lock, is a mechanic in Super Smash Flash 2 and Fraymakers that occurs when hitting a knocked down opponent with an attack dealing weak knockback. The opponent then remains on the ground momentarily before being forced to stand up slowly, which is also known as a jab reset or simply a reset.
Due to having to remain stationary while getting up, a forced getup leaves the opponent vulnerable for the player to follow up with a stronger attack, such as a KO move or a combo starter, as well as a grab in SSF2. Characters in SSF2 do not have any intangibility during a jab reset, whereas in Fraymakers, characters have the same amount of intangibility as with their normal floor getups.
A knocked down opponent can get hit by up to three weak attacks before being forced to stand up, with any additional attacks launching them normally. In Fraymakers, each of these three attacks causes the character to bounce against the ground, making them easier to hit momentarily.
Whether an attack will be able to cause a forced getup depends on various factors, such as its damage, knockback, and launch angle, as well as the knocked down character's size and weight. Some moves only do so in very specific circumstances, while others do so consistently. The most commonly used moves to cause forced getups are neutral attacks due to their almost universally weak knockback and minimal lag, as well as generally being able to hit any knocked down character. The weak hits of tilt attacks, smash attacks/strong attacks, and aerial attacks, as well as certain special moves, are also commonly used.
