A group text. Often you don't know that the text you received went out to a group of people and you respond without knowing that a lot of people will receive it.
I got a text from someone yesterday and I responded that I thought another guy was being an ass. I didn't know it was a Grext and it turns out that guy was on it. Looks like I'm the ass now.

My iPhone kept buzzing from new messages in the grext.

Grexting is so much better than texting.

The act of grinding and texting at the same time. You can inform the recipient they are being grexted or simply start the text with G:

Grocery-related texting, usually between long-term-committed couples; sometimes replaces or supersedes sexting in a relationship. May contain inside jokes, produce-related innuendo and/or #metaphorsforlife.

e.g.

- I'm at the farmers market. Want anything?

- How are the melons?

- Fresh and juicy. Same with the peaches. Do we have any courgettes at home?
- Yep. Very firm.

- I see some nice-sized pickles here.

- Leave the pickles. Bring your melons and peaches and hurry home.

- I'm coming!!!
