an acquaintance whom you see only about four times a year, typically every three calendar months, even though you generally get along jovially. The lack of more frequent camaraderie can be due to geographic distance, a lack of deeper connection, or as is most often the case - the passage of time in what was once a closer friendship
Yea, I was going to hit the bar with my buddy this Friday. I haven't seen him in months! He's more of a once-a-season friend.
