The art of seduction is full of subtle physical cues, subtly probing conversation and subconscious chemistry tests, or you can just skip the song and dance and drop a pickup line on whomever you like.
This method has a very low rate of success, but the recipient of your fabricated flirtation will definitely remember your attempt, no matter how feeble.
People took to the Reddits and shared some of the most creative ways they've been hit on, which generally involved some sort of "smooth" line that earned the line dropper a permanent place in the recipient's memory banks. Talk may be cheap, but at least it's free.
