I Know There's a Word for This

I know there's a word for this
I know there's a word for the way I'm feeling
I know there's a word for this
I know it, and it's on the tip of my tongue
And it won't go any further.

I know there's a word for this
I know, 'cause it's in the dictionary
And when I find what it is
I'll write it down in case it comes up again
I'll be certain to avoid it.

So, take this down:
I just feel so beat
And I think it's time
To admit defeat
I thought I got mine
But that uphill climbing
Is never through.

I know there's a word for this
I know 'cause we've all at sometime said it
Like when we were little kids
We'd fight each other 'til someone would give in
And you'd make him tell you 'uncle'.
