Jiggle peek
In one line: Stepping out of cover and back in quickly to see who is there, without giving them time to shoot.
What it means
A jiggle peek is a quick in-and-out: one step out and straight back in, sometimes several times. It is not for killing but for gathering information (is anyone there? where?) or for baiting a shot, especially from someone with a slow gun like the Operator.
Done well, the enemy only sees a sliver of you for an instant. Done badly (too slow, too wide), it is just a normal peek and a bullet in the head.
An example
You suspect an Operator is holding a long line. You jiggle peek: out and back in a flash. They fire and miss; now you know where they are and that they need to chamber another round, so your teammate can challenge them.
