(Spanish) An acronym used as a rough equivalent of the ubiquitous "LOL" in the southernmost region of Texas, generally known as "El Valle" and specifically encompassing Mission, La Joya, Mcallen, among others. The term appears to have been developed by one Chiflado while posting status updates on his Facebook and featured the term "RALG" or long hand "Riendome A Lo Gacho" which combined a literal use of "riendome"--which means "laughing"--with regional slang "gacho" -- an all purpose word that in this case means "alot". Thus Riendome A Lo Gacho=RALG.
Nambre, este vato ayer se puso bien pedo y se quito los pantalones adentro del club y el guey no traiba calzones, RALG LOL
!!! (translation) Man this dude was so drunk last night that he took his pants off at the club and he was not wearing underwear LOL!!!
