Cable channel MBC Music 'Gangnam Feel Dance Academy' will be revealing the secret behind Girls' Generation (SNSD)'s S lines. The secret was none other than the choreography of SNSD's 'I Got a Boy.'

'I Got a Boy' dance is called 'cobra dance' because the way they create waves by twisting their waists makes them look like cobras. The cobra dance is highly effective in getting rid of the extra fat around one's waist.

The students BTOB's Ilhoon, D-UNIT's Jin, and SKARF's Tasha became the masters of 'I Got a Boy' dance as they filmed for the academy. SKARF's Tasha, whose role model is SNSD's Yuri, said "I want to learn quickly."

The episode of these three mastering Wonder Girls' 'Like This' and SNSD's 'I Got a Boy' will be revealed today through cable channel MBC Music 'Gangnam Feel Dance Academy.'
