Diego landed The Triple Crown.
No way! What School?!
Yeah he fucked Erica, made out with Julie, and finger-banged Amanda, and Oak Hall!
But they're all best friends, dumb bitches.

the triple crown is a trophy in the six nations that only the 4 home nations of the tournament can win (england, ireland, scotland, wales) the most recent winners were ireland who won it in 2023 after beating england in dublin to win it back to back after their triumph in 2022 this time against scotland. scotland are the only home nation to not have lifted the triple crown but they have come close especially in 2023 when they beat wales and england but they just could not get the job done against ireland
