Royal Rainbow 

Related to "lasers" and "shoop da whoops", a "Royal Rainbow" is what happens when a taco is forced into the mouth of the person charging their laser. The caster instead releases a Royal rainbow, and possibly the swallowing of one's laser, and can end in the shooper asploding.

*Jered shoves taco in Phil's mouth*

*Phil releases Royal Rainbow*

Phil: OPS I SWALLOWED MAH LAZOR!

The highest level of excitement; it is often expressed with words or phrases like “full on” and “all the way.” Shouts of exclamation may accompany, creating laughter that is indecipherable from sobbing.

“TRIPLE rainbow excitement” is extremely rare and could cause you to spontaneously combust.

When I kissed Shannon goodnight for the first time I ran home jumping and yelling. That was some full-on double rainbow excitement, man!
