We were told during the August 1978 FOW, that the tea was called "stud" for allegedly being dosed with saltpeter (potassium nitrate, alleged in days of you to reduce male libido).
We were also taught that the strict rules for dining came from when A&M would admit 15 & 16 year-olds straight from a farm, who had no table manners at all. As in reaching for food without asking, talking with their mouths full, and so on.
The Standard would teach a person that the reason it was a Senior Privilege to walk on grass, as it was assumed they would be smart enough to not wear a rut across the lawns doing so.
Further, that Tessies, Midnight Yell, and fish matches were linked. In (really0 Old Army Days, cadets were to be in uniform near exclusively. Which would include a date to MYP. Since it was a violation (the old term-of-art was "RAM-able") to engage in a Public Display of Affection--such as holding hands, but, especially kissing.
The seniors, having wrangled dates from TWU (Tessies--from Texas State Teacher's School, now TWU) wanted to have an opportunity to kiss their dates without being detected. So, the Senior Yell leaders were to give a signal during MYP, so that their cohorts could douse the lights.
Now, the dateless seniors, with nothing better to do, could 'spoil the fun' by causing the "lights" to be on in a local sense, by having each freshman light a match.
Now, if a given zip suspected such would be the case, he might bum a match from the fish to prevent the planned osculation interruptus. The scheming 'stag' zip could then detail the fish to carry more matches, thus, ever to be ready to shine the light of day upon PDA.
I know, in the heat of that Autumn, that we learned to not buy 'safety' matches, and the striker chemistry on the side of the box was not sweat-resistant.
