A practice commonly used at the California Institute of Technology (Caltech) by men desiring female companionship. Due to the lopsided demographics (75% men, 25% women), one finds a dearth of women at Caltech. Thus, several men tend to court a woman at once. So, glomming refers to the practice of several men hooking onto (not literally) to one woman.
At a dance, one can find several men dancing with one woman. They are glomming her. Or, one might find several men walking to class with one woman. These men are glomming.
