Biology covers cells, organisms, reproduction and evolution, which means roughly half the vocabulary is already suggestive before anyone touches it. This is our full list of biology pick up lines, ranked by reader votes. They suit students, lab partners, medics and anyone who can name the parts of a cell without looking. Expect DNA jokes, mitochondria references that have long since become a meme, and several about natural selection that are cleverer than they first appear. The clean ones work in a lecture hall. The rest are best saved for the bar afterwards.
