A term marking the end of douche-baggery. After one has removed his or her goggles--either literally or figuratively--he or she is relieved of acting like, looking like, or feeling like a jackass. Generally used as a word of advice.
For literal situations:
S: Hey dude, I like your outift, especially your winter hat and welding goggles around your neck. It's silly and cool 'cause there's no need for either of those things right now!
B: Yeah, I think it's pretty cool too. You really like it?
S: No, take your goggles off, you look like a motherfucker.
For everyday "goggle" situations:
Perhaps you're at a party...
S: Hey, you're acting like a real ass... maybe this should be your last drink, 'cause you don't wanna be "that guy."
B: Don't tell me what to do! I'll drink more just to spite you.
S: Take your goggles off, man.
