Smugly

After googling around for a bit, and then switching to duckduckgo instead (Google becomes aggressively unhelpful as soon as you have words like "ejaculated" in your query. Duckduckgo does the same thing, just not quite so much.), it seems the book in question might be "The tenant of Wildfell Hall" by Emily Brontë.

By my analysis this meme required a set-up followed by a single complete line from a book.

With how doopid i am sometimes i feel like i also only ejaculate nonsense (into the genepool)
