One who is "gettin' it" cannot be criticized, because they are having one hell of a good time. However, while "gettin' it" you may look foolish.
When a group of people is really "gettin' it" look to join in on the fun.
Guy 2: Yea, dude looks life a fool.
Guy 3: He's going hard as fuck though.
Guy 1: Yea, he's gettin' it!
Student 1: Those kids are getting loud they better quiet down before a teacher yells at them.
(teacher walks across the gym floor to the loud students)
Student 2: There's the teacher.
Student 1: Look at her... she's gettin' it!
Also often used sarcastically. When it is obvious that the girl doesn't actually like the guy, people may assert that he is "gettin' it" even though he isn't. Prevalence increases when the girl enjoys leading the guy on.
