Etymology for “geezer” probably alternate of Scots “Guiser” ..meaning one in disguise.
Which probably described a bum on the street of which they would look out of the ordinary.
In present day I think it describes one who happens to be older ( depends on the group) than the others and or is eccentric ,loud, obnoxious,drunk,unreasonable person who frequently yells at others on the street and neighborhoods.
Grey facial stubble.
Unwashed shirt not properly tucked in.
