Your partner was playing an extended version of basic Jacoby Transfers, which is played by most people now.   I got this off a bridge conventions site for you:

 

Jacoby Transfers

Over partner's one notrump opening, responder bids

2D = transfer to hearts (shows at least 5 hearts)
2H = transfers to spades (shows at least 5 spades)

Following the transfer, responder bids

a. 2NT with values to invite to game in either the major or in NT (opener either passes, raises to game in NT or major, or bids 3 of the major to stop in part-score)
b. 3NT with value to force game in either major on in NT (partner either passes or raises to game in the major)
c. 3 of the major to invite game in the major alone
d. bids game in the major, showing either a very strong 5 card suit or 6+ trump support.

There are several extended Jacoby systems to show length in the minor.
a. 2S transfers to 3C, 3C transfer to 3D - simply continues the tranfer system
b. 2S - transfers to 3C, bidder may then correct to 3D (a direct bid of 3C or 3D shows game forcing strength)
c. Minor Suit Stayman
d. Four-Suit Transfers Additional OPTIONS that my be added to transfer sequences.

Your partner shouldn't have been rude, and hopefully you will meet again and give it another try.
