"Broadcasting from my room and and playin' with my toys" is double entendre which alludes to both mass shooters recording videos, and a camgirl using sex toys, which ties in both the theme of violence and oversexualization in American culture and relates to the previous line about "give me death or gimme head", which is also about violence and sex.
There are a load of double entendres/references to a first-person narrator bombing/shooting people, but they aren't vivid. Wiki says "...vivid and sustained discussion of controversial topics or anything that a reasonable person would consider as "heavy" should be considered as explicit." The point that should be argued here, if at all, is whether or not those are vivid.
