I can't stand the frowst in this room.

I love to frowst by the fireplace on a cold winter night.

The room was filled with frowsts.

She frowsts the cake before serving it.

She frowsted in bed all morning.

She is frowsting in her cozy bed.

The old attic had a frowsty smell.

The frowstiness of the room was unbearable.

The room is frowstier than before.

She has the frowstiest room in the house.
