1.
Synonym for 'random' - a person unknown to a group or one who says/does things which are inconsequential, makes contributions which are unconnected with the topic under discussion or behaves in ways which do not match the norms of a group or sub-culture.
Some randomer just walked in and left a plastic gnome on the bar.
