I believe it's referencing the statistic that women tend to use ODs as a preferred method over the more violent ways. I've seen incels quote that statistic and say "they do it because they have a good chance of being found in time to save them so it's just for attention." They're a sick bunch.
"What do you plan to do today, Becky?"
"Well, I'm going to starbucks, then I'm gonna tweet a bunch from there on my macbook, then maybe I'll OD on my pills again, watch some Netflix and get railed by some Chads"
