like-herpes

When you log into your social network of choice and find that one overly enthusiastic friend has "liked" a huge amount of photos or posts in a short period of time. If dealing with a not-quite-normal person, chronic "like-herpes" is possible.

"I had 40 notifications when I logged in this morning; Janet gave me like-herpes. I'm probably gonna put here in the same posting group as my mom for a while."
