Gig 'em in Texan maybe akin to aloha in Hawaiian
Gig 'em
Rather than end a conversation with "goodbye", many conversations between Aggies end with "gig 'em", usually accompanied by a thumbs up. This tradition began at a 1930 Midnight Yell Practice held before the football game against the Texas Christian University Horned Frogs. In an attempt to excite the crowd, Pinky Downs, a 1906 Texas A&M graduate and member of the school's Board of Regents, asked "What are we going to do to those Horned Frogs?" Using a term for frog hunting, he answered his own question, "Gig 'em, Aggies!" For emphasis, he made a fist with the thumb extended. The phrase and hand signal proved popular, and it became the first hand sign of the Southwest Conference. Gig 'em is also the name of one of the school yells, which is used during football kickoffs.
The university's traditions council recognizes another possible origin for the expression. The word "gig" is used in the US Army to indicate an infraction of the uniform code, and the A&M cadets used the same vocabulary. New cadets would quickly learn to fear being "gigged" during inspection for having unshined shoes, unpolished brass, or a non-aligned "gig line".
