1. Texas Red or sulforhodamine 101 acid chloride is a red fluorescent dye, used in histology for staining cell specimens, for sorting cells with fluorescent-activated cell sorting machines, in fluorescence microscopy applications, and in immunohistochemistry. Texas Red fluoresces at about 615 nm, and the peak of its absorption spectrum is at 589 nm. The powder is dark purple. Solutions can be excited by a dye laser tuned to 595-605 nm, or less efficiently a krypton laser at 567 nm. The absorption extinction coefficient at 596 nm is about 85,000 M−1cm−1.

2. Texas Red, a character in the country ballad Big Iron by Marty Robbins

2. In this town there lived an outlaw by the name of Texas Red
Many men had tried to take him and that many men were dead
He was vicious and a killer, though a youth of twenty four
And the notches on his pistol numbered one and nineteen more

3. Rolland "Red" Bastien had gone by the moniker Texas Red for a time, but I think Mark William Calaway might be the more famous wrestler to have used Texas Red as their ring name before he took on the mantle of The Undertaker.

The burning sensation in one's balloon knot after dropping a fire dookie. This extremely painful sensation is usually caused by power drinking while on a bender or extremely spicy food. Also may be caused by not properly cleaning after swamp ass.
While taking a shower, the water hit my Texas Red-Eye causing me to scream like a gay dude at a Cher concert.
