a fringe of hair cut straight across the forehead

she brushed back her wispy bangs

an act or instance of having sex

the character ‘!’

he began to bang the table with his fist

Sarah banged the phone down

someone was banging on the door

have sex with (someone)

cut (hair) in a fringe

(of music) have a loud, energetic beat that is good for dancing to

the train arrived bang on time

used to convey the sound of a sudden loud noise

party poppers went bang

used to convey the suddenness of an action or event

the minute something becomes obsolete, bang, it's gone
