friendship chocolate; chocolate given to a friend on Valentine's Day
Casual term used in the context of Valentine's Day in Japan, where women give chocolates to male friends without romantic intent, as opposed to 本命チョコ (romantic chocolate).
On Valentine's Day, I gave friendship chocolate to my male friends.
今年は友チョコを手作りしてみようかな。
Maybe I'll try making homemade friendship chocolate this year.
Compound of 友 (とも, 'friend') and チョコ, a shortening of チョコレート ('chocolate'). The term emerged from Japanese Valentine's Day culture to distinguish platonic chocolates from romantic ones.
