Jordan–Saudi Arabia border

The abruptly concave section of the boundary in the north is apocryphally named "Winston's Hiccup", also referred to as "Churchill's Sneeze" (Arabic: حازوقة وينستون).

In 1925 Britain and Ibn Saud signed the Treaty of Hadda, which created a border between Jordan and Saudi territory consisting of six straight lines.

[4][12][13] In the early 1960s, discussions were held which resulted in a treaty on 9 August 1965; thus creating the current boundary alignment of nine lines, as well as granting Jordan a slightly increased coast (by 18 km) along the Gulf of Aqaba.

[4] The urban myth of the 'Winston Hiccup' arose based on an account of Winston Churchill (then serving as the Secretary of State for the Colonies) boasting in his later years that he had created the British protectorate of Transjordan in 1921 "with the stroke of a pen, one Sunday afternoon in Cairo";[14] some stories purport that this drawing of the boundary took place following a "particularly liquid lunch".

[22][23] The “hiccup” resulted from giving the strategic Wadi Sirhan region, and its then primary settlement of Kaf, which had previously been occupied by Abdullah at the urging of the British, to the Sultanate of Nejd.

As already indicated, [Emir] Abdullah in that year had already established himself in Amman by his own initiative, when the British agreed to grant him a six-month option to demonstrate his ability to govern the Transjordanian territory as part of their Palestinian mandate.
