Whoop and Gig'em?

Can someone please explain Whoop and Gig’em ? History?

Whoop!: Aggie upperclassmen say this as an expression of approval. Freshman and sophomores are not supposed to say it.

Gig 'em: The hand sign is a closed fist with a thumb up. The tradition got its start in 1930 at a Yell Practice before a game against TCU. “Pinky” Downs, class of 1906, was a member of the A&M Board of Regents and gave a speech, asking the Aggies what they were going to do to the Horned Frogs. The term comes from hunting frogs or fish using a pronged spear called a “gig.”

Had to ask all mighty Google for the answer.

Here ya go. Lot’s of traditions. These are but a few
