Dalmation put it right. This guy has zero class. If you are this girls friend, reassure her that she can do better in life. No matter the time or place, one should have some compassion and let someone down easy. Especially if they have not harmed you in any way. Just show her support and advise her to move on. Time will heal her wounds and maybe in the end she'll be a knockout and that guy will be a lazy unemployed slob eating pizza in his mother's basement at the age of 38, all the while balding and lacking the ability to keep it up.

Good luck
