可以想成這樣一個畫面：你朝街對面一個男人抬了抬下巴，說「那個男的」。你不知道他叫什麼，也沒打算去問。這個字最原始的動作就是這個「指一下」。後面的各種意思，都像是那一下手勢裡多裝了一點東西：有時候裝的是年紀，有時候裝的是這個人在別人嘴裡的評價。From the word’s history
Wiktionary traces geezer to guiser, a person who goes about in costume or disguise. That fits the shrug: the word starts with someone whose real identity is not on show.
Wiktionary 把 geezer 追到 guiser——穿上戲服、把自己裝扮起來的人。這條線索正好對得上那個「指一下」的畫面：一開始指的，就是一個看不清楚底細的人。

老頭（美式、加拿大）
一樣是那個「指一下」，只是這一指把年紀也一起指了出來，而且常帶一點嫌他固執、跟不上時代的意思。
noun · C1
An old man. It is a casual, joking word that picks the man out by his age, and it usually hints that he is grumpy or old-fashioned.
老頭；老傢伙
