When you get a girl ridiculously drunk, and whilst she is chundering in a toilet you slip your willy in her vagina. You proceed to ride her of the convulsive movements of her body as she vomms. This can lead to a "thorgasm", the next stage in thunderchucking.

Both thorgasm and thunderchucking can be confused with norse mythology, but avast do not be baffled. Thunderchucking is a pun (play on words) of chunderfuck, thus humour ensues a-plenty. Suffice to say a night is only ever complete with the acheivement of one thunderchuck minimum, although jocularity is not always dependant on a thorgasm.

Get a thunderchuck mug for your mama Zora.
To be so intoxicated that when you spew, you take out not only your own cubicle but the entire bathroom.
