Please help me with these sentences 1. "A lethal weapon for mass-cultural change." Aldous saw the light at last and pumped a fist in front of him, trying to look Stalinesque and triumphant. (Aldous is watching a video of a vulgar man who he hate very much) I don't know what's the meaning of this sentence. 2. In the meantime, several kind baby boomer ladies had taken pity on him.(he just divorced, but it seems many women like him) I don't know what's the meaning of baby boomer ladies, is there any profound meaning of it, or it just means women born in a generation with too many babies. Thank you~
