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!
To use the words yep and/or yeah an excessive amount in one sentence.
A statement of affirmation or agreement about a proposed activity. Used in place of "I could get behind that", or "sure". The 'yeah' can be omitted if in a hurry.
While originally used exclusively about objects that are 'splayable', modern uses of the phrase do not require this property.
A similar phrase is "yeah, I *can* splay that", used to indicate belief or proficiency instead, i.e. "I'd buy it" or "I can do that".
It's also theoretically possible to use "no, I couldn't/can't/won't splay that" to indicate distaste or refusal, but this is rarely heard.
person A: ayo we're going Wendys in 10, you down?
person B: *deliberates* yeah, i could splay that
