Title text: Well, sex is like a velociraptor: despite your movie-fueled lifelong neurotic obsession, unlikely to be found in your house.
Megan describes her relationship to Cueball with the simile "our love is like a turtle," a comparison often made when referring to a shy and slowly developing yet steady sort of romance. However, Cueball thinks that the Brontosaurus is a better comparison. His explanation refers to the fact that remains of Apatosaurus were by mistake believed to be a different genus, which the paleontologist O.C. Marsh named Brontosaurus. It was later discovered that the two genera should be classified as one, with the older name prevailing according to convention . The term Brontosaurus therefore became a scientific redundancy.
Applied to the scenario in the comic, Cueball apparently considers the relationship without any emotional foundation and only continues it out of nostalgic motives. This conclusion counteracts the initial romantic tone adopted by the turtle simile, as comparing a romance with a falsely classified fossil is one of the least charming statements imaginable. 
The title text aims at Randall's well-known enthusiasm for Velociraptors. Megan retorts by comparing any future sex between the two of them to be as likely as finding a Velociraptor in his house. The insult has a second barb: painting Cueball as being obsessed with movies involving Velociraptors.
However the status of "Brontosaurus" remains under discussion, with a 2015 study of diplodocids reporting that the more gracile fossils should be classified in a separate genus, which would then be Brontosaurus.
