Rainbow Row

When a group of girls wearing different colored lipsticks go down on a group of guys, leaving a ring of colors on their junk resembling a rainbow.

"Dude you missed out on rainbow row last night! My penis looked like a skittles commercial"

rainbow sponge 

dope.

"I hope you buy a rainbow sponge and it doesn't work!" said Hope to Danielle.

Basically, Hope said that she hopes Danielle buys some drugs, but they aren't drugs; they're fake drugs.

Rainbow Summer

The explosion of gay marriages during the summer of 2015 in reaction to the Supreme Court decision legalizing gay marriages throughout the United States. (Even in Texas!)

I am excited about going to Jenny and Deanna's wedding during Rainbow Summer because we've been waiting for so many years to officially celebrate it.
