Oliver

The name of someone who contributes little to nothing to a group chat. Olivers tend to sit around all day just viewing things like little weasels. A nuclear strike could be happening but guaranteed an Oliver will just be waiting around, anticipating someone to type something.

Person 1: "Look at this fella, just viewing our messages"
Person 2: "Oh my giddy gosh, he's such an Oliver"
Person 3: "Oh wow, look at Insert name here, he's so cool and the ladies love him, he messages back in the group and doesn't sit back and watch like an absolute wally"
