It's extremely common for programmers especially to add -er endings to common verbs to describe functions or objects that do that thing. Even if you want to exclude the playful neologisms that use this -er ending (Googler, Redditer) you have only to dig into the archives of classic code to find plenty of examples of this and it usually means "one who X's", in this case, "one who gropes".
