Future posting 

When used on messageboards, notably Collegehumor's, it means that some douche has gotten a first by commenting before the picture/article/video has gone national

Days-Of-Future-Pasting

When a movie in a series has events that nullify the events shown in some or all of the preceding movies.

Taken from the 2014 film X-Men: Days Of Future Past where events in the film cancelled out 5 of the preceding 6 films (X-Men 1, 2, 3, Origins, The Wolverine).

"Hey, man; have you seen the new trailer for Terminator: Genisys? If old Arnie is going back to confront young Arnie, then Paramount Pictures are Days-Of-Future-Pasting the other four movies."

Futureposting 

When you’re hurt and need to publicly be toxic about it

“Ay is ya boi good? He just got dumped.”
“Yeah he’ll be fine, he’s just going to be futureposting for awhile”
“Use my mouth for what? So I can taste your past? Nah eat these kids and taste the future”
