The popular drinking trend has worried colleges around the region this year. Ahead of the Boston Marathon on Monday, Boston College and Boston University are urging students to make smart decisions amid the festivities — especially here in the year of the BORGs. “We do not recommend drinking a BORG,” Sarah Voorhees, assistant director of substance use, recovery, and sexual well-being at Boston University, told BU Today, the on-campus news outlet. BORGs, or “blackout rage gallons,” have become the drinking fad of choice for college students this year, with their popularity advertised on TikTok, alarming doctors, health experts, and school administrators. Both institutions are hosting on-campus, marathon-related events on Monday and are encouraging students to attend those festivities instead.
