A spanish word created by Jorgito. the word bonar has many definitions not only does it mean to hang out with friends. many times you can use this word in place of pasar tiempo con mis amigos. also you can use this word as to fuck. many spanish people do not consider this a word do to its vulgarity. Bonar is a member of the -ar- family and has regular conjugations.
yo bono mis amigos-- meaning i hang out with my friends

Yo bonar cesars madre--- meaning i fuck charlies mom...that would be disgusting tho because she is lesbian, also charlie has two mommies but thats a different story
