what my brain says in a conversation when it can think of anything else
Other Person - *shit I don't care about*
Me - yeah
A word used when you have absolutely no idea of what others are talking about, usually accompanied with a stupid look and a half open mouth:
Jeff: a seyfert galaxy, 65789000978765 million light years away from us was swallowed by the 43001 black hole, 6556378 years ago!!!!
Joe: yeah, yeah!
Cross between a yak and a rabbit.
Yeah but, the possibilities are limitless..
What you sarcastically grumble when everyone in a group seems to wanna get all cozy for no apparent reason.
(Spoken while dutifully cooperating in a huge "crowd embrace" of party-goers just to be polite and agreeable, but not really understanding why everyone wants to get all cozy) "Yeah, yeah, yeah --- arms around... aren't we all huggy-cuddly-snuggly LOVEY-DOVEY today!!"
