I finally sussed what #GOFWN hashtag means (and, yeah, duh).
Should be more widely used. Ideal for when people interrupt threads. Seems to be dominated by one person.

@SheepOverboard Get Off.... Get Out From....Get Over Forward...
Meh. I give up.

@DachshundSaidSo - are you actually trying to guess? If so, visit the hashtag & it becomes clear.

@SheepOverboard Well yeah... Guessing is how I do pretty much everything. Doesn't everyone?
