Simultoke 

Simultoke, two or more people smoking a toke at the same time. This can be done using 2 or more bongs, pipes, buckets, parachutes, ect... but is only a sumultoke if both tokes are lit at the same time.

Go to www.youtube.com/watch?v=FVZYmbJt7Ho and watch the video. When the music pauses, the three people are smoking a simultoke.

simultaneous equation 

equations involving two or more unknowns that are to have the same values in each equation.

If an equation has two unknowns, such as 2y + x = 20, it cannot have unique solutions. Two unknowns require two equations which are solved at the same time (simultaneously) − but even then two equations involving two unknowns do not always give unique solutions.
This gives us a 'simultaneous equation'
