Social Media Jargon Buster
Gadget
Same as a widget (although one fewer point in Scrabble).
Google Bomb
When the same keyword is inserted in the anchor text in hundreds of blogs and sites in the hope of influencing the Google search engine. Bit like Rick-Rolling.
Grassroots Marketing
Building a relationship with influencers in your key market and getting them to actively advocate its use.
Groups
In the 80's, Groups tended to have poodle perms and sport low-cut lycra t-shirts. Nowadays, internet Groups are collections of people brought together online because of similar interests, goals or concerns.
