Get the asstime mug.
The combination of ass dialing and FaceTiming. The act does not necessarily have to be specifically caused by the gluteus maximus, but can refer to any accidental cause. Usually makes for extremely awkward moments and always happens when you are talking about the person or place you AssTimed. Not to be confused with "sexting".
Steph: "How did I FaceTime Cook's Cafe??"
Tyler: "Hahaha, it looks like you AssTimed the local diner... aaaaawkward"

Get the AssTime mug.
A hasty response to a request for data or information, such as project time-frames or costs, that has the appearance of being relevant and well considered while in actuality being largely baseless and pulled from thin air.

Similar to a guesstimate but lacking any forthright element, pull-it-out-of-your-asstimates are typically a response to an unreasonable request or means of quickly escaping an otherwise long, drawn-out and pointless discussion.
Even though I haven't seen any of the requirements or initial design documents the boss wouldn't stop hassling me for a scope of work. I had to give him a pull-it-out-of-your-asstimate of 4 weeks to get him off my case so I could start figuring our what it's really going to take.
