High Frequency

The act of getting a full on erection from the movie "Radio"

Paul had High Frequency when his parents, wife, children and pastor came into the room to have their weekly chili dinner.

I decided to use the High Frequency (HF) radio last night and try my luck at reaching Japan.

Playing the high frequencies 

An idiom used to describe the moment of downturn for a previously successful enterprise/musician/actor etc. A clear, defining point which, when reached, means nothing will be the same again.

Similar to 'Jumping the Shark' or 'Nuking the Fridge'.

From Loud Reed and his wife staging a high frequency dog concert ("an inter-species social gathering").....

Yeah man, they were really playing the high frequencies that time.
