Jab grab

The jab grab (abbreviated "JG") is a character-specific technique performable by Pikachu, Mario, Ness, and Fox in Smash 64, done by abusing the shield stun of a jab. It is performed by jabbing, and then using a grab instantly afterwards. The jab cancel must be done fast enough to grab the enemy while he/she is still in shield stun. Additionally, performing the grab too late will just perform another jab instead. It is a simple form of shield pressure, though it can be used when connecting with anay damageable object.
Level 8-9 computer opponents occasionally use this technique as well, more often with Mario.
This technique is highly useful in competitive play, and it is one of the key reasons why certain characters are considered better at pressuring, as not having this technique highly limits shield pressure.
