look up anything, like your first name:
1. Blueberries
To come up with a complete non-sequitor in a conversation. The entymology of this word began on The Geek Show Podcast when panelist Leigh George Kade would be accused of completely derailing conversations with completely irrelevant information. One day, when he wasn't there, a fellow panelist decided to "fill in" for him and shouted "Blueberries!" for no reason.

It's caught on with the audience of the show and is a recurring declaration when an irrelevant, derailing comment is made.
I'm calling blueberries on that.

You totally just blueberried.

Those are blueberry shenanigans.
2. Blueberries
A word use to end a conversation that is going nowhere or is redundant.
We already talked about this...Blueberries
3. Blueberries
A great strand of dank cannabis.
I just smoked a Blueberry blunt to the dome.

5. Blueberries
A bunch of fangirls from ONTD (who have since spun off into their own community) that showed photos of their junk/boobs to Eli Roth on MySpace in return for his leering approval.
Those Blueberries just sent Eli Roth a picture of their tits! Shameless harlots!
