Something that shouldn't be on the Enterprise-D. I mean, they're in SPACE! The Enterprise-D is the flagship of Starfleet, so why do they need to imagine they're in 20th century San Francisco when they can be screwing green women?
A groupchat who are all One Direction fans who can't spell properly because they are illterate hoes. You can also call them for short hdtp which is the initials for the groupchat.
Someone who goes on holiday, then proceeds to tweet and post statuses with content that is deliberatelyintended to make you jealous, and does so effectively.

To open the door to the bathroom and walk away while someone is sitting on the toilet...preferably during a dinner party or other social gathering. The effect is to both embarrass and paralyze the person being holodecked. Crew members of StarTrek probably do this to new crew members.
