The feeling of breathlessness one gets when a romantic gesture is made. Nothing can be done to stop the feeling which is likened to a gas canister exploding in the chest.

Once you have 'Love Asthma' nothing can be done to cure this feeling - it will hit you from time to time, rendering you useless and unable to carry out normal day-to-day activities.
