there is a medical explanation for this
"Alcohol is a testosterone stimulant and the affect it has on women is based upon the fact that testosterone is not the dominant hormone in the female make-up, therefore they are usually unable to control the affect of testosterone as men do on a daily, even hourly, basis. Dealing with the bravado that testosterone produces is not a common experience to a woman and therefore they rarely know how to cope with it. This explains why they are more prone to carrying out acts that are normally not in their nature when drinking. The stimulation of testosterone initially makes them loud as the bravado affect kicks in; a feeling of invincibility that leads them to drop all inhibitions follows this. If there is a dance floor they are liable to seek it as a challenge to dance with a view to drawing self-attention. They meet with strangers when stimulated testosterone has them feeling invincible and there is no need for me to point out the dangers that this can create."
