When a guy/girl is bent over their phone, while in stature that resembles the appearance of a sea horse (and usually on social media).
That guy has been seahorsing on his phone for an hour.
That girl looks like a seahorse when she surfs Facebook on her phone.
You seahorsed a lot last night while you were drunk.
