MC Jin ABC lyrics

Part of the lyrics I need translating:
Here is a stanza section of the lyrics for context:
你話我唔係正宗唐人　Who are you 啲鬼佬睇我又咪係黃皮膚
雖然我哋環境係兩個唔同世界 但係分別好少　
你唔好踩得就踩
八月十五同中秋節 舊曆新曆根本就無分別
新年流流咪又係逗吓利是
飲吓茶打幾圈 唔係嘅咪鋤 Dee
歐陽靖究竟係邊個 你真係想知　
最清楚係我 簡單唻講　三個字　邊三個

Here is the lines I have trouble understanding:
你唔好踩得就踩
飲吓茶打幾圈 唔係嘅咪鋤 Dee (what is 鋤 Dee?)
- Should 飲吓茶 be 飲下茶？

Thx.
