I ran along this sentence while reading a novel online. To put it into context, 3 guys were drinking beer at home to celebrate something. Guy 1 had his arm around Guy 2's neck in a friendly way. Guy 2 then said this.
I'm slightly beyond a beginner in terms of a japanese but the only part I understand here is the 早く. As far as I know, 外さねー has mupltiple meanings and the biggest problem is I don't know what オト here is supposed to be.
If this info helps at all, Guy 2 was in his 20s while Guy 1 was in his 30s
