chemgasm 

The intense sensation of pleasure, ecstasy, euphoria and relief experienced when understanding or discovering a chemistry related phenomenon.

Often this fortunate event is accompanied by vocalisations and uncontrolled body movements.

'I wish I could chemgasm as easily as you can!'

'I just had a huge chemgasm after Collinsons tutorial today'

'I faked a chemgasm last night when Bob was explaining spin orbital coupling to me'

Chewgasm 

The orgasmic feeling ladies get while listening to "The Chewy Experience".

"Oh my god, I was listening to "The Chewy Experience" the other day and I totally had a chewgasm."
